Answer to Question 1

B
Feedback:
Construct validity refers to the degree to which an instrument has an appropriate sample of items for the construct being measured. An instrument's content validity is based on the judgment of experts evaluating the instrument. There is no totally objective method for insuring adequate content coverage, but often a panel of subject content experts is asked to evaluate the content validity of new instruments. An instrument is internally consistent to the extent that its items measure the same trait. Equivalence, in reliability assessment, primarily concerns the degree to which two or more independent observers or coders agree about scoring on an instrument. In criterion-related validity assessments, researchers examine the relationship between scores on an instrument and an external criterion.

B
