Q98

When responses on two comparable sets of measures tapping the same construct are highly correlated, it is called as

A) Parallel-form reliability
B) Discriminant Validity

Q100

Problem with measures of test-retest reliability is that; if the time between the measures is long, there may be ______________

A) Maturation of the subjects
B) Uniformity in attitude and immoderation of the subjects
C) Uniformity in attitude
D) Immoderation of the subjects

AI Explanation
