Content validity is a type of validity, not reliability.

Parallel-forms reliability is the correlation between two different forms of a test that are administered to the same group of people at the same time.

Sample size is not a factor that can affect the reliability of a test.

Face validity, content validity, construct validity, and criterion validity are all types of validity.

Validity is the degree to which a test measures what it is supposed to measure.

Test content is not a factor that can affect the validity of a test.

Criterion validity is the correlation between a test score and a criterion measure.

Face validity is not a type of criterion validity.

Reliability is the degree to which a test is free from measurement error.

Test difficulty is not a factor that can affect the reliability of a test-retest reliability coefficient.

Test-retest reliability is the degree to which a test is consistent across different administrations.

Test content is not a factor that can affect the reliability of a parallel-forms reliability coefficient.

Inter-rater reliability is the degree to which a test is consistent across different raters.

Split-half method is not a factor that can affect the reliability of a split-half reliability coefficient.

Fairness is the degree to which a test is free from bias.
