When well integrated into your argument, evidence helps prove that you've done your research and thought critically about your topic. But what's the best way to introduce evidence so it feels seamless and has the highest impact? There are actually quite a few effective strategies you can use, and we've rounded up the best ones for you here. Try some of the tips below to introduce evidence in your essay and make a persuasive argument.

Things You Should Know

• "According to..."
• "The text says..."
• "Researchers have learned..."
• "For example..."
• "[Author's name] writes..."

Setting up the Evidence

• You can use 1-2 sentences to set up the evidence, if needed, but usually more concise you are, the better.

• For example, you may make an argument like, “Desire is a complicated, confusing emotion that causes pain to others.”
• Or you may make an assertion like, “The treatment of addiction must consider root cause issues like mental health and poor living conditions.”

• For example, you may write, “The novel explores the theme of adolescent love and desire.”
• Or you may write, “Many studies show that addiction is a mental health issue.”

Putting in the Evidence

• For example, you may use an introductory clause like, “According to Anne Carson…”, "In the following chart...," “The author states…," "The survey shows...." or “The study argues…”
• Place a comma after the introductory clause if you are using a quote. For example, “According to Anne Carson, ‘Desire is no light thing" or "The study notes, 'levels of addiction rise as levels of poverty and homelessness also rise.'"
• A list of introductory clauses can be found here: https://student.unsw.edu.au/introducing-quotations-and-paraphrases .

• For example, you may write, “In the novel, Carson is never shy about how her characters express desire for each other: ‘When they made love/ Geryon liked to touch in slow succession each of the bones of Herakles' back…’”
• Or you may write, "The study charts the rise in addiction levels, concluding: 'There is a higher level of addiction in specific areas of the United States.'"

• For example, you may write, “Carson views events as inevitable, as man moving through time like “a harpoon,” much like the fates of her characters.”
• Or you may write, "The chart indicates the rising levels of addiction in young people, an "epidemic" that shows no sign of slowing down."

• For example, you may write in the first mention, “In Anne Carson’s The Autobiography of Red , the color red signifies desire, love, and monstrosity.” Or you may write, "In the study Addiction Rates conducted by the Harvard Review...".
• After the first mention, you can write, “Carson states…” or “The study explores…”.
• If you are citing the author’s name in-text as part of your citation style, you do not need to note their name in the text. You can just use the quote and then place the citation at the end.

• If you are paraphrasing a source, you may still use quotation marks around any text you are lifting directly from the source.

• For example, you may write, “In the novel, the characters express desire for each other: ‘When they made love/ Geryon liked to touch in slow succession each of the bones of Herakles' back (Carson, 48).”
• Or you may write, "Based on the data in the graph below, the study shows the 'intersection between opioid addiction and income' (Branson, 10)."
• If you are using footnotes or endnotes, make sure you use the appropriate citation for each piece of evidence you place in your essay.

• You may also mention the title of the work or source you are paraphrasing or summarizing and the author's name in the paraphrase or summary.
• For example, you may write a paraphrase like, "As noted in various studies, the correlation between addiction and mental illness is often ignored by medical health professionals (Deder, 10)."
• Or you may write a summary like, " The Autobiography of Red is an exploration of desire and love between strange beings, what critics have called a hybrid work that combines ancient meter with modern language (Zambreno, 15)."

• The only time you should place 2 pieces of evidence together is when you want to directly compare 2 short quotes (each less than 1 line long).
• Your analysis should then include a complete compare and contrast of the 2 quotes to show you have thought critically about them both.

Analyzing the Evidence

• For example, you may write, “In the novel, Carson is never shy about how her characters express desire for each other: ‘When they made love/ Geryon liked to touch in slow succession each of the bones of Herakles' back (Carson, 48). The connection between Geryon and Herakles is intimate and gentle, a love that connects the two characters in a physical and emotional way.”
• Or you may write, "In the study Addiction Rates conducted by the Harvard Review, the data shows a 50% rise in addiction levels in specific areas across the United States. The study illustrates a clear connection between addiction levels and communities where income falls below the poverty line and there is a housing shortage or crisis."

• For example, you may write, “Carson’s treatment of the relationship between Geryon and Herakles can be linked back to her approach to desire as a whole in the novel, which acts as both a catalyst and an impediment for her characters.”
• Or you may write, "The survey conducted by Dr. Paula Bronson, accompanied by a detailed academic dissertation, supports the argument that addiction is not a stand alone issue that can be addressed in isolation."

• For example, you may write, “The value of love between two people is not romanticized, but it is still considered essential, similar to the feeling of belonging, another key theme in the novel.”
• Or you may write, "There is clearly a need to reassess the current thinking around addiction and mental illness so the health and sciences community can better study these pressing issues."

About This Article

Before you introduce evidence into your essay, begin the paragraph with a topic sentence. This sentence should give the reader an overview of the point you’ll be arguing or making with the evidence. When you get to citing the evidence, begin the sentence with a clause like, “The study finds” or “According to Anne Carson.” You can also include a short quotation in the middle of a sentence without introducing it with a clause. Remember to introduce the author’s first and last name when you use the evidence for the first time. Afterwards, you can just mention their last name. Once you’ve presented the evidence, take time to explain in your own words how it backs up the point you’re making. For tips on how to reference your evidence correctly, keep reading!

What this handout is about

This handout will provide a broad overview of gathering and using evidence. It will help you decide what counts as evidence, put evidence to work in your writing, and determine whether you have enough evidence. It will also offer links to additional resources.

Introduction

Many papers that you write in college will require you to make an argument ; this means that you must take a position on the subject you are discussing and support that position with evidence. It’s important that you use the right kind of evidence, that you use it effectively, and that you have an appropriate amount of it. If, for example, your philosophy professor didn’t like it that you used a survey of public opinion as your primary evidence in your ethics paper, you need to find out more about what philosophers count as good evidence. If your instructor has told you that you need more analysis, suggested that you’re “just listing” points or giving a “laundry list,” or asked you how certain points are related to your argument, it may mean that you can do more to fully incorporate your evidence into your argument. Comments like “for example?,” “proof?,” “go deeper,” or “expand” in the margins of your graded paper suggest that you may need more evidence. Let’s take a look at each of these issues—understanding what counts as evidence, using evidence in your argument, and deciding whether you need more evidence.

What counts as evidence?

Before you begin gathering information for possible use as evidence in your argument, you need to be sure that you understand the purpose of your assignment. If you are working on a project for a class, look carefully at the assignment prompt. It may give you clues about what sorts of evidence you will need. Does the instructor mention any particular books you should use in writing your paper or the names of any authors who have written about your topic? How long should your paper be (longer works may require more, or more varied, evidence)? What themes or topics come up in the text of the prompt? Our handout on understanding writing assignments can help you interpret your assignment. It’s also a good idea to think over what has been said about the assignment in class and to talk with your instructor if you need clarification or guidance.

What matters to instructors?

Instructors in different academic fields expect different kinds of arguments and evidence—your chemistry paper might include graphs, charts, statistics, and other quantitative data as evidence, whereas your English paper might include passages from a novel, examples of recurring symbols, or discussions of characterization in the novel. Consider what kinds of sources and evidence you have seen in course readings and lectures. You may wish to see whether the Writing Center has a handout regarding the specific academic field you’re working in—for example, literature , sociology , or history .

What are primary and secondary sources?

A note on terminology: many researchers distinguish between primary and secondary sources of evidence (in this case, “primary” means “first” or “original,” not “most important”). Primary sources include original documents, photographs, interviews, and so forth. Secondary sources present information that has already been processed or interpreted by someone else. For example, if you are writing a paper about the movie “The Matrix,” the movie itself, an interview with the director, and production photos could serve as primary sources of evidence. A movie review from a magazine or a collection of essays about the film would be secondary sources. Depending on the context, the same item could be either a primary or a secondary source: if I am writing about people’s relationships with animals, a collection of stories about animals might be a secondary source; if I am writing about how editors gather diverse stories into collections, the same book might now function as a primary source.

Where can I find evidence?

Here are some examples of sources of information and tips about how to use them in gathering evidence. Ask your instructor if you aren’t sure whether a certain source would be appropriate for your paper.

Print and electronic sources

Books, journals, websites, newspapers, magazines, and documentary films are some of the most common sources of evidence for academic writing. Our handout on evaluating print sources will help you choose your print sources wisely, and the library has a tutorial on evaluating both print sources and websites. A librarian can help you find sources that are appropriate for the type of assignment you are completing. Just visit the reference desk at Davis or the Undergraduate Library or chat with a librarian online (the library’s IM screen name is undergradref).

Observation

Sometimes you can directly observe the thing you are interested in, by watching, listening to, touching, tasting, or smelling it. For example, if you were asked to write about Mozart’s music, you could listen to it; if your topic was how businesses attract traffic, you might go and look at window displays at the mall.

An interview is a good way to collect information that you can’t find through any other type of research. An interview can provide an expert’s opinion, biographical or first-hand experiences, and suggestions for further research.

Surveys allow you to find out some of what a group of people thinks about a topic. Designing an effective survey and interpreting the data you get can be challenging, so it’s a good idea to check with your instructor before creating or administering a survey.

Experiments

Experimental data serve as the primary form of scientific evidence. For scientific experiments, you should follow the specific guidelines of the discipline you are studying. For writing in other fields, more informal experiments might be acceptable as evidence. For example, if you want to prove that food choices in a cafeteria are affected by gender norms, you might ask classmates to undermine those norms on purpose and observe how others react. What would happen if a football player were eating dinner with his teammates and he brought a small salad and diet drink to the table, all the while murmuring about his waistline and wondering how many fat grams the salad dressing contained?

Personal experience

Using your own experiences can be a powerful way to appeal to your readers. You should, however, use personal experience only when it is appropriate to your topic, your writing goals, and your audience. Personal experience should not be your only form of evidence in most papers, and some disciplines frown on using personal experience at all. For example, a story about the microscope you received as a Christmas gift when you were nine years old is probably not applicable to your biology lab report.

Using evidence in an argument

Does evidence speak for itself.

Absolutely not. After you introduce evidence into your writing, you must say why and how this evidence supports your argument. In other words, you have to explain the significance of the evidence and its function in your paper. What turns a fact or piece of information into evidence is the connection it has with a larger claim or argument: evidence is always evidence for or against something, and you have to make that link clear.

As writers, we sometimes assume that our readers already know what we are talking about; we may be wary of elaborating too much because we think the point is obvious. But readers can’t read our minds: although they may be familiar with many of the ideas we are discussing, they don’t know what we are trying to do with those ideas unless we indicate it through explanations, organization, transitions, and so forth. Try to spell out the connections that you were making in your mind when you chose your evidence, decided where to place it in your paper, and drew conclusions based on it. Remember, you can always cut prose from your paper later if you decide that you are stating the obvious.

Here are some questions you can ask yourself about a particular bit of evidence:

• OK, I’ve just stated this point, but so what? Why is it interesting? Why should anyone care?
• What does this information imply?
• What are the consequences of thinking this way or looking at a problem this way?
• I’ve just described what something is like or how I see it, but why is it like that?
• I’ve just said that something happens—so how does it happen? How does it come to be the way it is?
• Why is this information important? Why does it matter?
• How is this idea related to my thesis? What connections exist between them? Does it support my thesis? If so, how does it do that?
• Can I give an example to illustrate this point?

Answering these questions may help you explain how your evidence is related to your overall argument.

How can I incorporate evidence into my paper?

There are many ways to present your evidence. Often, your evidence will be included as text in the body of your paper, as a quotation, paraphrase, or summary. Sometimes you might include graphs, charts, or tables; excerpts from an interview; or photographs or illustrations with accompanying captions.

When you quote, you are reproducing another writer’s words exactly as they appear on the page. Here are some tips to help you decide when to use quotations:

• Quote if you can’t say it any better and the author’s words are particularly brilliant, witty, edgy, distinctive, a good illustration of a point you’re making, or otherwise interesting.
• Quote if you are using a particularly authoritative source and you need the author’s expertise to back up your point.
• Quote if you are analyzing diction, tone, or a writer’s use of a specific word or phrase.
• Quote if you are taking a position that relies on the reader’s understanding exactly what another writer says about the topic.

Be sure to introduce each quotation you use, and always cite your sources. See our handout on quotations for more details on when to quote and how to format quotations.

Like all pieces of evidence, a quotation can’t speak for itself. If you end a paragraph with a quotation, that may be a sign that you have neglected to discuss the importance of the quotation in terms of your argument. It’s important to avoid “plop quotations,” that is, quotations that are just dropped into your paper without any introduction, discussion, or follow-up.

Paraphrasing

When you paraphrase, you take a specific section of a text and put it into your own words. Putting it into your own words doesn’t mean just changing or rearranging a few of the author’s words: to paraphrase well and avoid plagiarism, try setting your source aside and restating the sentence or paragraph you have just read, as though you were describing it to another person. Paraphrasing is different than summary because a paraphrase focuses on a particular, fairly short bit of text (like a phrase, sentence, or paragraph). You’ll need to indicate when you are paraphrasing someone else’s text by citing your source correctly, just as you would with a quotation.

When might you want to paraphrase?

• Paraphrase when you want to introduce a writer’s position, but their original words aren’t special enough to quote.
• Paraphrase when you are supporting a particular point and need to draw on a certain place in a text that supports your point—for example, when one paragraph in a source is especially relevant.
• Paraphrase when you want to present a writer’s view on a topic that differs from your position or that of another writer; you can then refute writer’s specific points in your own words after you paraphrase.
• Paraphrase when you want to comment on a particular example that another writer uses.
• Paraphrase when you need to present information that’s unlikely to be questioned.

When you summarize, you are offering an overview of an entire text, or at least a lengthy section of a text. Summary is useful when you are providing background information, grounding your own argument, or mentioning a source as a counter-argument. A summary is less nuanced than paraphrased material. It can be the most effective way to incorporate a large number of sources when you don’t have a lot of space. When you are summarizing someone else’s argument or ideas, be sure this is clear to the reader and cite your source appropriately.

Statistics, data, charts, graphs, photographs, illustrations

Sometimes the best evidence for your argument is a hard fact or visual representation of a fact. This type of evidence can be a solid backbone for your argument, but you still need to create context for your reader and draw the connections you want them to make. Remember that statistics, data, charts, graph, photographs, and illustrations are all open to interpretation. Guide the reader through the interpretation process. Again, always, cite the origin of your evidence if you didn’t produce the material you are using yourself.

Do I need more evidence?

Let’s say that you’ve identified some appropriate sources, found some evidence, explained to the reader how it fits into your overall argument, incorporated it into your draft effectively, and cited your sources. How do you tell whether you’ve got enough evidence and whether it’s working well in the service of a strong argument or analysis? Here are some techniques you can use to review your draft and assess your use of evidence.

Make a reverse outline

A reverse outline is a great technique for helping you see how each paragraph contributes to proving your thesis. When you make a reverse outline, you record the main ideas in each paragraph in a shorter (outline-like) form so that you can see at a glance what is in your paper. The reverse outline is helpful in at least three ways. First, it lets you see where you have dealt with too many topics in one paragraph (in general, you should have one main idea per paragraph). Second, the reverse outline can help you see where you need more evidence to prove your point or more analysis of that evidence. Third, the reverse outline can help you write your topic sentences: once you have decided what you want each paragraph to be about, you can write topic sentences that explain the topics of the paragraphs and state the relationship of each topic to the overall thesis of the paper.

For tips on making a reverse outline, see our handout on organization .

Color code your paper

You will need three highlighters or colored pencils for this exercise. Use one color to highlight general assertions. These will typically be the topic sentences in your paper. Next, use another color to highlight the specific evidence you provide for each assertion (including quotations, paraphrased or summarized material, statistics, examples, and your own ideas). Lastly, use another color to highlight analysis of your evidence. Which assertions are key to your overall argument? Which ones are especially contestable? How much evidence do you have for each assertion? How much analysis? In general, you should have at least as much analysis as you do evidence, or your paper runs the risk of being more summary than argument. The more controversial an assertion is, the more evidence you may need to provide in order to persuade your reader.

Play devil’s advocate, act like a child, or doubt everything

This technique may be easiest to use with a partner. Ask your friend to take on one of the roles above, then read your paper aloud to them. After each section, pause and let your friend interrogate you. If your friend is playing devil’s advocate, they will always take the opposing viewpoint and force you to keep defending yourself. If your friend is acting like a child, they will question every sentence, even seemingly self-explanatory ones. If your friend is a doubter, they won’t believe anything you say. Justifying your position verbally or explaining yourself will force you to strengthen the evidence in your paper. If you already have enough evidence but haven’t connected it clearly enough to your main argument, explaining to your friend how the evidence is relevant or what it proves may help you to do so.

Using evidence.

Like a lawyer in a jury trial, a writer must convince her audience of the validity of her argument by using evidence effectively. As a writer, you must also use evidence to persuade your readers to accept your claims. But how do you use evidence to your advantage? By leading your reader through your reasoning.

The types of evidence you use change from discipline to discipline--you might use quotations from a poem or a literary critic, for example, in a literature paper; you might use data from an experiment in a lab report.

The process of putting together your argument is called analysis --it interprets evidence in order to support, test, and/or refine a claim . The chief claim in an analytical essay is called the thesis . A thesis provides the controlling idea for a paper and should be original (that is, not completely obvious), assertive, and arguable. A strong thesis also requires solid evidence to support and develop it because without evidence, a claim is merely an unsubstantiated idea or opinion.

This Web page will cover these basic issues (you can click or scroll down to a particular topic):

• Incorporating evidence effectively.
• Integrating quotations smoothly.
• Citing your sources.

Incorporating Evidence Into Your Essay

When should you incorporate evidence.

Once you have formulated your claim, your thesis (see the WTS pamphlet, " How to Write a Thesis Statement ," for ideas and tips), you should use evidence to help strengthen your thesis and any assertion you make that relates to your thesis. Here are some ways to work evidence into your writing:

• Offer evidence that agrees with your stance up to a point, then add to it with ideas of your own.
• Present evidence that contradicts your stance, and then argue against (refute) that evidence and therefore strengthen your position.
• Use sources against each other, as if they were experts on a panel discussing your proposition.
• Use quotations to support your assertion, not merely to state or restate your claim.

Weak and Strong Uses of Evidence

In order to use evidence effectively, you need to integrate it smoothly into your essay by following this pattern:

• State your claim.
• Give your evidence, remembering to relate it to the claim.
• Comment on the evidence to show how it supports the claim.

To see the differences between strong and weak uses of evidence, here are two paragraphs.

Weak use of evidence

Today, we are too self-centered. Most families no longer sit down to eat together, preferring instead to eat on the go while rushing to the next appointment (Gleick 148). Everything is about what we want.

This is a weak example of evidence because the evidence is not related to the claim. What does the claim about self-centeredness have to do with families eating together? The writer doesn't explain the connection.

The same evidence can be used to support the same claim, but only with the addition of a clear connection between claim and evidence, and some analysis of the evidence cited.

Stronger use of evidence

Today, Americans are too self-centered. Even our families don't matter as much anymore as they once did. Other people and activities take precedence. In fact, the evidence shows that most American families no longer eat together, preferring instead to eat on the go while rushing to the next appointment (Gleick 148). Sit-down meals are a time to share and connect with others; however, that connection has become less valued, as families begin to prize individual activities over shared time, promoting self-centeredness over group identity.

This is a far better example, as the evidence is more smoothly integrated into the text, the link between the claim and the evidence is strengthened, and the evidence itself is analyzed to provide support for the claim.

Using Quotations: A Special Type of Evidence

One effective way to support your claim is to use quotations. However, because quotations involve someone else's words, you need to take special care to integrate this kind of evidence into your essay. Here are two examples using quotations, one less effective and one more so.

Ineffective Use of Quotation

Today, we are too self-centered. "We are consumers-on-the-run . . . the very notion of the family meal as a sit-down occasion is vanishing. Adults and children alike eat . . . on the way to their next activity" (Gleick 148). Everything is about what we want.

This example is ineffective because the quotation is not integrated with the writer's ideas. Notice how the writer has dropped the quotation into the paragraph without making any connection between it and the claim. Furthermore, she has not discussed the quotation's significance, which makes it difficult for the reader to see the relationship between the evidence and the writer's point.

A More Effective Use of Quotation

Today, Americans are too self-centered. Even our families don't matter as much any more as they once did. Other people and activities take precedence, as James Gleick says in his book, Faster . "We are consumers-on-the-run . . . the very notion of the family meal as a sit-down occasion is vanishing. Adults and children alike eat . . . on the way to their next activity" (148). Sit-down meals are a time to share and connect with others; however, that connection has become less valued, as families begin to prize individual activities over shared time, promoting self-centeredness over group identity.

The second example is more effective because it follows the guidelines for incorporating evidence into an essay. Notice, too, that it uses a lead-in phrase (". . . as James Gleick says in his book, Faster ") to introduce the direct quotation. This lead-in phrase helps to integrate the quotation with the writer's ideas. Also notice that the writer discusses and comments upon the quotation immediately afterwards, which allows the reader to see the quotation's connection to the writer's point.

REMEMBER: Discussing the significance of your evidence develops and expands your paper!

Citing Your Sources

Evidence appears in essays in the form of quotations and paraphrasing. Both forms of evidence must be cited in your text. Citing evidence means distinguishing other writers' information from your own ideas and giving credit to your sources. There are plenty of general ways to do citations. Note both the lead-in phrases and the punctuation (except the brackets) in the following examples:

Quoting: According to Source X, "[direct quotation]" ([date or page #]).

Paraphrasing: Although Source Z argues that [his/her point in your own words], a better way to view the issue is [your own point] ([citation]).

Summarizing: In her book, Source P's main points are Q, R, and S [citation].

Your job during the course of your essay is to persuade your readers that your claims are feasible and are the most effective way of interpreting the evidence.

Questions to Ask Yourself When Revising Your Paper

• Have I offered my reader evidence to substantiate each assertion I make in my paper?
• Do I thoroughly explain why/how my evidence backs up my ideas?
• Do I avoid generalizing in my paper by specifically explaining how my evidence is representative?
• Do I provide evidence that not only confirms but also qualifies my paper's main claims?
• Do I use evidence to test and evolve my ideas, rather than to just confirm them?
• Do I cite my sources thoroughly and correctly?

Academic writing often requires students to use evidence, and learning how to use evidence effectively is an important skill for college writers to master. Often, the evidence college writers are asked to use comes from their textbooks, course readings, or other written work by professional scholars. It is important to learn how to use these writings responsibly and accurately.

General Considerations

There are three methods of incorporating the writing of others into your paper as evidence:

• quotation , which is anything from a word to several sentences taken word-for-word from the original source and enclosed in quotation marks
• paraphrase , which is a rephrasing in your own voice and sentence structure of one portion of the original source and is about the same length as the original sentence or sentences you are paraphrasing
• summary , which is shorter than the original source and gives the text’s central idea in your own words

Some words to use in signal phrases are argues, asserts, contends, emphasizes, explains, observes, suggests, writes.

In what follows, you will learn some strategies for using these methods of incorporating evidence into your paper.

In Practice

When you use a quotation as evidence, you should integrate it into your own writing using a “signal phrase.” Take, for example, this quotation, taken from page 418 of the essay “Prejudice and the Individual” by Gordon Allport: “Much prejudice is caught rather than directly taught.” Here are three ways to integrate Allport’s quotation into a sentence of your own with a signal phrase:

Allport claims that “prejudice is caught rather than directly taught” (418). “Much prejudice is caught rather than directly taught,” claims Allport (418). “Much prejudice,” Allport claims, “is caught rather than directly taught” (418).

You can adapt a quotation to fit your own paragraph and sentence structure by making small changes to words and indicating those changes with square brackets. Say, for example, you liked this quotation from Allport:

“It should be added that overgeneralized prejudgments of this sort are prejudices only if they are not reversible when exposed to new knowledge” (417).

However, you want to apply Allport’s words to a specific example of your own. You could adapt the quotation like this:

The young man in my example was not prejudiced, according to Allport’s definition; his opinion was “reversible when [he was] exposed to new knowledge” (417).

You can also use ellipses to indicate that you have left irrelevant words out of a quotation. Again, say you wanted to use this quotation from Allport:

“The best opinion today says that if we eliminate discrimination, then—as people become acquainted with one another on equal terms—attitudes are likely to change, perhaps more rapidly than through the continued preaching or teaching of tolerance” (417).

But the middle part is less important to your paper than what Allport says at the start and the end. You could modify the quotation like this:

“The best opinion today says that if we eliminate discrimination . . . attitudes are likely to change, perhaps more rapidly than through the continued preaching or teaching of tolerance” (417).

Longer quotations must be formatted in a special way; usually, they are indented from the left margin and/or single-spaced. Depending on what citation style you use, guidelines differ regarding what defines a long quotation and how a long quotation should be formatted. Typically, a quotation of four or five lines is considered long.

Paraphrasing

To paraphrase a source for use as evidence, you should use as little of the original language as possible and put the passage in your own voice and sentence structure. Also, because paraphrasing involves wrapping your words around someone else’s idea, people often forget to give credit to the author. Even though a paraphrase is in your words, it is not your idea. Remember to cite your source when you paraphrase. Here is another quotation from Allport and an example of weak and strong paraphrase:

“Education combats easy overgeneralizations, and as the educational level rises we find a reduction in stereotyped thinking” (Allport 422).

WEAK PARAPHRASE: Learning fights against stereotypes, and as more people are more educated we notice a decrease in prejudice (422).

STRONG PARAPHRASE: Allport explains that the more we learn, the harder we will find it to make unfair assumptions about groups of people, which means as more people pursue more education, prejudice decreases (422).

In the weak example above, you can see the sentence structure in the paraphrase is very similar to the quotation—notice, for instance, the use in both the original sentence and the weak paraphrase of a comma plus the conjunction “and.” Also, the replacement of Allport’s words with synonyms makes the paraphrase too close to the original—Allport’s “education” is replaced with “learning” in the paraphrase; his “combats” is exchanged for “fights”; “overgeneralizations” becomes “stereotypes.” The strong example above does a better job of restating Allport’s idea in a new sentence structure and without simple word substitution. Also, notice the weak paraphrase does not give Allport credit by mentioning him, but the strong one does.

Summarizing

When you summarize another writer’s idea to use as evidence in a paper of your own, you are taking the essence of the writer’s idea and stating it more briefly, with less detail and explanation, than in the original. You may summarize an article or a chapter, or even a book, in a sentence, a paragraph, a page, or more—the purpose of your summary should dictate how specific you are. Summaries should be mostly in your own words, but often summaries include quotations or paraphrases when it is necessary to highlight a certain key point. When you are writing a summary, you need to be very careful not to use the original writer’s words without putting those words in quotation marks. You also need to be sure that when you summarize, you are fairly representing the original writer’s main idea. Here is a paragraph from Allport and examples of weak and strong summary:

“While discrimination ultimately rests on prejudice, the two processes are not identical. Discrimination denies people their natural or legal rights because of their membership in some unfavored group. Many people discriminate automatically without being prejudiced; and others, the “gentle people of prejudice,” feel irrational aversion, but are careful not to show it in discriminatory behavior. Yet in general, discrimination reinforces prejudices, and prejudices provide rationalizations for discrimination. The two concepts are most distinct when it comes to seeking remedies. The corrections for discrimination are legal, or lie in a direct change of social practices; whereas the remedy for prejudice lies in education and the conversion of attitudes. The best opinion today says that if we eliminate discrimination, then—as people become acquainted with one another on equal terms—attitudes are likely to change, perhaps more rapidly than through the continued preaching or teaching of tolerance.” (Allport 417)

WEAK SUMMARY: Discrimination is when people are denied their rights because they belong to some unfavored group, and it is addressed with legal action or a change in social practices. Eliminating discrimination from society would have a drastic effect on social attitudes overall, according to Allport (417).

STRONG SUMMARY: Allport explains that discrimination occurs when an individual is refused rights because he or she belongs to a group which is the object of prejudice. In this way, discrimination reinforces prejudice, but if instances of discrimination are ruled illegal or seen as socially unacceptable, prejudice will likely decrease along with discrimination (417).

You will notice that the weak summary above uses exact words and phrases from the source (“unfavored group,” “social practices”) and also some words and phrases very close to the original (“when people are denied,” “eliminating discrimination”). It does not effectively restate the original in different language. It also does not fairly represent the complete idea of the source paragraph: it does not explain the relationship between discrimination and prejudice, an important part of what Allport says. The strong example does a better job using independent language and fairly conveying Allport’s point.

How to choose which method of incorporating evidence to use

These methods of incorporating evidence into your paper are helpful in different ways. Think carefully about what you need each piece of evidence to do for you in your paper, then choose the method that most suits your needs.

You should use a quotation if

• you are relying on the reputation of the writer of the original source to give authority or credibility to your paper.
• the original wording is so remarkable that paraphrasing would diminish it.

A paraphrase is a good choice if

• you need to provide a supporting fact or detail but the original writer’s exact words are not important.
• you need to use just one specific idea from a source and the rest of the source is not as important.

Summary is useful when

• you need to give an overview of a source to orient your reader.
• you want to provide background that leads up to the point of your paper.

Last but certainly not least, remember that anytime you use another person’s ideas or language, you must give credit to that person. If you do not know the name of the person whose idea or language you are using, you must still give credit by referring to a title or any such available information. You should always check with your instructor to see what method of citing and documenting sources you should use. The examples on this handout are cited using MLA style.

The sample text in these exercises is Holly Devor’s “Gender Role Behaviors and Attitudes.”

1. Read the paragraph from Devor below, then identify which summary of it is weak and which is strong.

“Body postures and demeanors which communicate subordinate status and vulnerability to trespass through a message of "no threat" make people appear to be feminine. They demonstrate subordination through a minimizing of spatial use: people appear to be feminine when they keep their arms closer to their bodies, their legs closer together, and their torsos and heads less vertical than do masculine-looking individuals. People also look feminine when they point their toes inward and use their hands in small or childlike gestures.” (486)

A. Devor argues that body language suggests a great deal about gender and power in our society. People who minimize the body space they occupy and whose physical gestures are minimal and unobtrusive appear inferior and feminine (486).

B. Devor says that body postures and demeanors that imply weakness make people look feminine. Minimizing the space one takes up and using infantile gestures also makes one appear feminine (486).

2. Read the sentence from Devor below, then identify which paraphrase of it is weak and which is strong.

“They demonstrate subordination through a minimizing of spatial use: people appear to be feminine when they keep their arms closer to their bodies, their legs closer together, and their torsos and heads less vertical than do masculine-looking individuals.” (486)

A. Devor explains that people demonstrate a lesser position by using less space, keeping arms close, legs together, and head less upright (486).

B. According to Devor, taking up less space with one’s body—keeping arms and legs close and hunching to reduce height—makes one appear inferior and implies femininity (486).

3. The quotations of Devor below, taken from the paragraph in exercise 1, contain technical errors. Identify and correct them.

A. Devor argues that “[b]ody postures and demeanors which communicate subordinate status and vulnerability make people appear to be feminine” (486).

B. The actress looked particularly feminine because she “point their toes inward and use their hands in small or childlike gestures” (486).

C. Devor claims that “using their hands in small or childlike gestures” makes people look feminine (486).

Answers: 1. A. STRONG B. WEAK – This example uses too many exact words and phrases from the original.

2. A. WEAK – This example uses too many exact words and phrases from the source, and its sentence structure is also too close to the original. B. STRONG

3. A. Devor argues that “[b]ody postures and demeanors which communicate subordinate status and vulnerability . . . make people appear to be feminine.” B. The actress looked particularly feminine because she “point[s her] toes inward and use[s her] hands in small or childlike gestures.” C. Devor claims that “us[ing] their hands in small or childlike gestures” makes people look feminine.

What Is Evidence in an Essay?

If you want to learn how to introduce evidence in an essay, you have come to the right place. We promise to list all the essential things you need to be familiar with in order to compose an ideal academic essay . But before we turn to this particular topic, we would like to first discuss the essence of this term. Introducing evidence in an essay is a way of providing reliable and credible support for the argument or point of view taken. Professional paper writers understand that it is essential to use the right kind of evidence to back up a claim. This helps to make the argument more convincing and strengthens its validity.

Evidence forms the strongest foundation on which your essay statements can stand. It is absolutely important that every writer backs up his or her arguments with quotes, diagrams, tables, paraphrases from reliable sources, and so on. If they are not present in a text, readers are unlikely to consider the work in question professional.

Various Types of Evidence

To learn how to introduce your evidence in an essay, you should first get familiar with the different proof categories. All of them can be highly beneficial for supporting your ideas in an assignment. Although you can use an essay writing service , we believe it will be very helpful if you get familiar with the different categories. We guarantee that after reading the following sections, you will find it much easier to introduce evidence into your essay.

Testimonial

To make your academic paper even more reliable, you should consider listing the opinion of one or more experts in the particular field you are focusing on. An example of an experienced individual would be someone who has a degree in the field in question. Integrating evidence through testimonials will make your work look very professional and credible.

Another reasonable way to introduce evidence in an essay is to describe real-life experiences. Readers usually find these very intriguing, and many authors try to capture readers’ interest by including a series of personal stories or case studies. It is not a good idea to use anecdotal evidence alone, as it is not as reliable as the other options listed in this section.

This particular type is widely used and is considered one of the most useful ones when it comes to poetry analysis, for example. You can support your claims by adding quotes from books, poems, reports, and so on. Once you learn how to introduce evidence in an essay via textual references, you will find it easier to introduce the other types of evidence discussed here.

In contrast to the one listed above, logical evidence is often said to be the weakest option when it comes to supporting one’s ideas. When you choose to support an argument with logic, you are essentially presenting a hypothetical conclusion. Authors should always support their beliefs with other things, such as case studies, quotes, diagrams, etc.

Statistical

This is definitely one of the most commonly used types of support. In the simplest terms, this particular variant relies on statistics. It shows that the author has done his best to gather data from various sources. Moreover, such numerical charts or tables are quite hard to refute. They are usually presented at the beginning of an essay in order to attract the reader’s attention from the very beginning. Those are commonly used in the process of writing an academic essay, which is quite understandable, considering how useful and informative they can be.

Analogies are a great way to introduce your views on a particular topic. Incorporating evidence using comparisons is a common practice, and many authors believe it works wonders. Simply put, a writer explains his or her concepts by comparing two similar objects or situations. It is best to choose an object that is already familiar to the reader. This way, it will be easier for him to understand your arguments.

How Can I Introduce Evidence in an Essay?

One of the most important things you should do when writing classification essays or any other type of paper, you should first create a plan you will stick to throughout the entire time. One of the essential things you should consider is how to present evidence in an essay. Here is our step-by-step guide on introducing evidence that will be of great help to you.

• Introduce the topic of your essay to readers.
• Use an argument and introduce your evidence by mentioning the name of the writer and the respective work of his.
• Citing evidence should never begin with a quote. Instead, be sure to use words or phrases such as according to, as cited by, as [author’s name] says in his book, and so on.
• When you introduce a textual reference in your essay, be sure to reproduce all quotations verbatim and put them in quotation marks.
• Right after introducing evidence to your paper, provide further information about it.
• Elaborate on why you have decided to use this book, article, statistics, or poem as a reference.
• Sum up the paragraph with a sentence that will conclude your idea.

Key Phrases for Introducing Evidence

To learn how to state evidence in an essay, you should familiarize yourself with a few key phrases that should always be present in an academic paper. As mentioned earlier, a writer should never begin directly with a citation. Regardless of whether you work on diagnostic essay writing or poetry analysis, you should always introduce your sources with the help of special phrases. Here are some of them:

As [author’s name] indicated in his study…

As stated by the author…

In accordance with what the poet says in his work…

According to the writer…

As mentioned in the book…

This particular source makes it clear that…

The writer claims that…

As shown in the statistics…

This research shows that…

For example,…

As can be seen on page 18, the writer claims that…

As he points out in his study…

Dos and Don’ts in Integrating Evidence Into the Essay

We hope that you already know the answer to the question: How do you present evidence in an essay? Nevertheless, we thought it would be best to go over the most important aspects writers should consider when they introduce their ideas using citations, diagrams, etc. Additionally, if you are in a rush and need a paper written quickly, there are many last-minute paper writing services available to help you.

First and foremost, you should never introduce your evidence with a quote, as we have already mentioned. Make sure that you use enough important introductory phrases in your analysis. Also, when writing essays, make sure that you are very familiar with the topic at hand. This way, you will have no trouble elaborating on the research papers, books, or articles you use to support your beliefs.

Moreover, it is important to edit your paper online for any mistakes or inconsistencies. This way, you can ensure that your essay is free of errors and reads smoothly. Additionally, online editing tools can help you to accurately cite any sources you use, giving your essay an extra layer of credibility.

Using Research and Evidence

Welcome to the Purdue OWL

What type of evidence should I use?

There are two types of evidence.

First hand research is research you have conducted yourself such as interviews, experiments, surveys, or personal experience and anecdotes.

Second hand research is research you are getting from various texts that has been supplied and compiled by others such as books, periodicals, and Web sites.

Regardless of what type of sources you use, they must be credible. In other words, your sources must be reliable, accurate, and trustworthy.

How do I know if a source is credible?

You can ask the following questions to determine if a source is credible.

Who is the author? Credible sources are written by authors respected in their fields of study. Responsible, credible authors will cite their sources so that you can check the accuracy of and support for what they've written. (This is also a good way to find more sources for your own research.)

How recent is the source? The choice to seek recent sources depends on your topic. While sources on the American Civil War may be decades old and still contain accurate information, sources on information technologies, or other areas that are experiencing rapid changes, need to be much more current.

What is the author's purpose? When deciding which sources to use, you should take the purpose or point of view of the author into consideration. Is the author presenting a neutral, objective view of a topic? Or is the author advocating one specific view of a topic? Who is funding the research or writing of this source? A source written from a particular point of view may be credible; however, you need to be careful that your sources don't limit your coverage of a topic to one side of a debate.

What type of sources does your audience value? If you are writing for a professional or academic audience, they may value peer-reviewed journals as the most credible sources of information. If you are writing for a group of residents in your hometown, they might be more comfortable with mainstream sources, such as Time or Newsweek . A younger audience may be more accepting of information found on the Internet than an older audience might be.

Be especially careful when evaluating Internet sources! Never use Web sites where an author cannot be determined, unless the site is associated with a reputable institution such as a respected university, a credible media outlet, government program or department, or well-known non-governmental organizations. Beware of using sites like Wikipedia , which are collaboratively developed by users. Because anyone can add or change content, the validity of information on such sites may not meet the standards for academic research.
