Which of the following is NOT a type of validity?

Statistical validity is not typically classified as a type of validity in the context of psychometrics. Instead, validity in psychometrics generally refers to how well a test or assessment measures what it is intended to measure. The three recognized types of validity are content validity, construct validity, and criterion-related validity.

Content validity assesses whether the content of a test is representative of the domain it aims to measure, ensuring that all aspects of the construct are covered. Construct validity evaluates whether the test truly measures the theoretical construct it claims to measure and includes evidence that supports the relationship between the test and other measures consistent with that construct.

Criterion-related validity examines how well one measure predicts an outcome based on another measure, typically assessing the effectiveness of a test in practical applications, such as predicting job performance based on test scores.

While statistical techniques may be involved in assessing these types of validity, they do not themselves constitute a form of validity.
