Assume that you have developed a study technique that you believe will result in students scoring higher on research methods exams. You test your study technique with the design diagrammed below.
R = random assignment
0 = observation
X = stimulus

R 01 X 02
R 03 04

Using the diagrammed design, what predictions will you make?
A) 02 should be greater than 01.
B) 02 should be less than 04.
C) 04 should be greater than 03.
D) 04 should be less than 01.

The design follows a pretest-posttest control group design, with random assignment of participants to either the treatment group (receiving the study technique) or control group (no intervention). Therefore, the prediction would be that the posttest score (02) of the treatment group should be higher than the pretest score (01), because of the study technique. The other predictions (B, C, and D) cannot be made based on this design.
