AP PSYCHOLOGY

Detailed explanation-1: -Face validity is the extent to which a measurement method appears “on its face” to measure the construct of interest.

Detailed explanation-2: -What is criterion validity? To evaluate criterion validity, you calculate the correlation between the results of your measurement and the results of the criterion measurement. If there is a high correlation, this gives a good indication that your test is measuring what it intends to measure.

Detailed explanation-3: -Content validity refers to the extent to which the items on a test are fairly representative of the entire domain the test seeks to measure.

Detailed explanation-4: -Validity will tell you how good a test is for a particular situation; reliability will tell you how trustworthy a score on that test will be. You cannot draw valid conclusions from a test score unless you are sure that the test is reliable. Even when a test is reliable, it may not be valid.

Detailed explanation-5: -Validity refers to whether a test measures what it aims to measure. For example, a valid driving test should include a practical driving component and not just a theoretical test of the rules of driving.
