An investigation of a test's construct validity may yield evidence that
A) the test is measuring a single construct.
B) the test does not correlate significantly with another test purporting to measure the same construct.
C) test scores increase as a function of age.
D) All of these

All three options are indicators of construct validity. A test that measures a single construct is more likely to be valid, as it shows that the test is measuring what it is supposed to. A lack of correlation with another test measuring the same construct suggests that the test is not simply measuring some other unrelated variable. Finally, if test scores increase as a function of age, it suggests that the construct being measured is developing as expected over time, which provides additional evidence for the validity of the test.
