What Is Evidence Quality in Writing?

Evidence quality is about how strong and relevant your support is. Better evidence makes your point more believable and more useful to readers.

Why this metric matters

Specific examples are usually stronger than broad general statements.
Evidence should directly support the point you are trying to prove.
Strong support becomes even better when you explain what it shows.

How to improve it

Use facts, examples, observations, or data that clearly match your point.
Choose support that a reader can picture or evaluate, not vague claims.
Avoid dropping evidence into the essay without explaining it.
Ask whether each example proves the point or merely mentions the topic.

Evidence quality example

Specific evidence is stronger than saying "some animals help things" because it shows exactly how the support works.
