Accepted Answer

The degree to which a test measures the theoretical construct it claims to measure

Question 2

What does 'convergent validity' evidence demonstrate?

Accepted Answer

That a test correlates highly with other measures of the same construct

Answer

Convergent validity is supported when a test correlates strongly with other measures that theoretically assess the same construct.

Question 3

What is 'discriminant validity'?

Accepted Answer

Evidence that a test does NOT correlate highly with measures of different constructs

Answer

Discriminant validity is demonstrated when a test shows low correlations with measures of theoretically unrelated constructs.

Question 4

What is a 'scale score' in standardized testing?

Accepted Answer

A transformed score designed to be comparable across test forms and administrations

Answer

Scale scores are transformed from raw scores to provide a common metric that allows meaningful comparisons across different test forms and administrations.
