c. well the instrument measures the construct.
14. Which of the following is one type of validity?
a. content
b. internal
c. equivalence
15. The type of validity investigated depends on the
a. size of the sample.
b. frequency of data sampling.
c. purpose of the measure.
16. Which of the following refers to how well a instrument's items truly measure the subject?
