For this assignment, you will design four quasi-experimentsa nonequivalent control group design, a nonequivalent control group pretest/posttest design, an interrupted time-series design, and a nonequivalent groups interrupted time-series designto test the following statement:

Joining a fraternity or sorority causes students to become more concerned with their physical appearance.

Explain how you would design each study (this can be in paragraph format or laid out as a diagram) and create a hypothetical table of each studys results. Finally, using the three causal criteria, explain whether or not each study can support the causal statement.

• Nonequivalent Groups Interrupted Time-Series Design

  • Study Design

  • Table of Results

  • Can this design support the causal claim?
