<h3>content validity - how well a test measures the behavior for which it is intended</h3>
Example -
<em>A mathematics teacher develops an end-of-semester algebra test for her class. The test should cover every form of algebra that was taught in the class. If some types of algebra are left out, then the results may not be an accurate indication of students’ understanding of the subject. Similarly, if she includes questions that are not related to algebra, the results are no longer a valid measure of algebra knowledge.</em>
Another example is that content validity can be used in a clinical or business setting
