Refers to the extent to which a measure represents all facets of a given construct. It is assessed by expert judgment and may involve a systematic analysis of the test content.

Assesses whether a test reflects a certain set of abilities in a current or future setting as measured by some criterion. It usually involves correlational studies ($r$) and may be split into concurrent and predictive validity.

Determines how well a test or tool measures the construct that it was designed to measure. This type of validity is assessed through hypothesis testing, factor analysis, correlation with other measures, and sometimes experimental manipulation.

Measures if the test appears to test what it is supposed to test. It is more about what the test superficially appears to measure rather than its scientific validity and is assessed by laypeople's judgment.

A form of criterion validity that assesses how well a test compares to a well-established measure administered at the same time. It is evaluated using correlation coefficients with existing known standards.

Examines how well a score on a test predicts future performance. Predictive validity is often assessed by correlating test outcomes with performance measured at a later time ($r$).

Part of construct validity, this measures whether a test correlates highly with other tests believed to measure the same construct. It's assessed by examining the correlation of the focal test with different measures of the same construct.

Another aspect of construct validity, discriminant validity assesses the degree to which concepts or measurements that are supposed to be unrelated are, in fact, unrelated. It involves demonstrating low correlation between unrelated measures.

This type of validity assesses whether an observed effect can be attributed specifically to the variable of interest, rather than to other extraneous variables. It is often assessed through rigorous experimental control and randomization.
