Discuss a step-by-step approach for the procedure in the experiment. For example, Some researchers outlined steps typically used in the procedure for a pretest-posttest control group design with matching participants in the experimental and control groups:
1. Administer measures of the dependent variable or a variable closely correlated with the
dependent variable to the research participants.
2. Assign participants to matched pairs on the basis of their scores on the measures described in
Step 1.
3. Randomly assign one member of each pair to the experimental group and the other member to the
control group.
4. Expose the experimental group to the experimental treatment and administer no treatment or an
alternative treatment to the control group.
5. Administer measures of the dependent variables to the experimental and control groups.
6. Compare the performance of the experimental and control groups on the posttest(s) using tests of
statistical significance.
