Q53: A researcher predicts that additional study time will increase achievement. This is a:

Q54: A researcher states that study time and achievement are related but does not specify whether the relationship is positive or negative. This is:

Q55: A test produces highly consistent scores but does not actually measure the intended construct. The test is best described as:

Q56: Research reliability refers primarily to:

Q64: Which pair concerns consistency rather than accuracy?

Q65: Internal validity primarily concerns:

Q66: External validity is primarily concerned with:

Q67: A newly developed test is compared with an already validated test measuring the same characteristic. Strong correlation supports:
