Types of Evidence

Whether writing an informational/explanatory or argumentative essay, knowing which evidence appropriately supports the topic sentence of each body paragraph is essential. Teach your students to follow the CARVO guidelines in selecting and using essay evidence.

• The evidence needs to be Consistent with other evidence within the same source. Evidence needs to have internal validity. In other words, the evidence must fit other evidence presented within the same source.
• The evidence must be Accurate and unquestionable. Use other sources to double check accuracy. Not all sources are reliable.
• The evidence has be Relevant. Appropriate evidence must directly relate to the topic. It may only be used when the context of your source matches the context of how you use the evidence in your writing.
• The evidence has to be Varied and balanced to convince your audience. Provide both quantitative and qualitative data. Use both primary and secondary sources.
• The evidence has to be Objective and fairly presented. Never use slanted or biased evidence to prove your point. Save the argument or interpretation of the evidence for your analysis of that evidence.

Teaching your students how to select and use evidence is a process. Student writers often fail to consider the importance of their audience in deciding what and how to support their body paragraph topic sentences. You might try this story to help them make the connection:

A friend of yours went on a backpack and saw a UFO hovering over a valley. The spacecraft landed and the aliens came out to greet the earthlings. 

To convince your peers about what your friend experienced, what evidence would they require?

When I students how to write evidence in essay body paragraphs, I tell them to imagine themselves as a jury in a murder trial. Each juror will be convinced by different types of evidence. Some lean on eyewitness testimony; others only trust forensic evidence; one or two may be swayed by the logic of circumstantial Wouldn’t it make sense for a prosecuting attorney to reach out to all juror interests to make her case?

Similarly, student writers need to consider the needs of their audience in the types of evidence they include in essay body paragraphs. Following are eight types of evidence with a clever memory trick for students to reference. Of course, not all eight types of evidence would be appropriate for all argumentative (CCSS W 1.0) and informational-explanatory (CCSS W 2.0) essays.

Types of Evidence: FE SCALE C

1. Fact means something actually done or said.

Neil Armstrong was the first person to step on the moon. He said, “That’s one small step for a man, one giant leap for mankind.”

2. Example is a part of something used to explain the whole thing.

Peas, beans, and corn are examples of vegetables.

3. Statistic is an amount, fraction, or percentage learned from scientific research.

The world has over 7 billion people; half live in Asia; only 5% live in the United States.

4. Comparison means to show how one thing is like or unlike another.

Both automobiles are available with hybrid engines, but only one has an all-electric plug-in option.

5. Authority is an expert which can be quoted to support a claim or a topic.

According to the Surgeon General of the United States, “Smoking is the chief cause of lung cancer.”

6. Logic is deductive (general to specific) or inductive (specific to general) reasoning.

All fruits have vitamins and apples are fruits, so apples have vitamins. The first 10 crayons I picked were red, so the whole box must be filled with red crayons.

7. Experience is a personal observation of or participation in an event.

Hiking to the bottom of the Grand Canyon and back requires careful planning and takes most of the day.

8. Counterclaim is the argument against one’s point of view, which the writer then minimizes or refutes (proves wrong).

Some argue that a high protein diet is healthy because… However, most doctors disagree due to…
