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 greater than 04.
C)04 should be greater than 03.
D)02 should be greater than 01 and 04

This design is a pretest-posttest randomized control group design, where participants are randomly assigned to either the experimental group (who receive the X stimulus) or the control group (who do not). The pretest (01) measures the participants' initial level of knowledge on research methods, and the posttest (02 and 04) measures their knowledge after the experimental group receives the study technique. Therefore, we can predict that 02 should be greater than both 01 (due to potential practice effects) and 04 (due to the effectiveness of the study technique). There is no basis for predicting that 02 should be greater than 03 since group 03 is not receiving the study technique.
