Pretests provide a direct measure of change over time.

Explanation:

Pretest and post test are part of experimental design.

Experiments design are framework formed to plan about the experiment. so that steps and observation of experiment can be controlled and inference and can be most accurately deduced.

While there are many experimental design, the problem here is concerned about pretest and post test control group design.

In pretest test data about outcome is noted before any experiment is observed.

In post test data of outcome is noted after the experiment.

Almost every experiment include pretest and post methodology of experimental design to gauge differences in result and determine accurate behavior of experiment under study.

Hence, based on this Pretests provide a direct measure of change over time. is wrong option as the time is not an important fact here.
