1. Identify the research scenario including the relevant independent variable (which would have already occurred) and dependent variable.
2. Develop the appropriate primary research question to be associated with this design.
3. Discuss how the statistical procedures control technique will be used as a means to assign participants to each group. Discuss the rationale for this technique.
4. Ex post facto is unique in that it is non-experimental research but aspects of internal validity still apply. Discuss the major threats to validity associated with this design and type of research (non-experimental).
5. Enter the relevant variables in the chart below.
6. Briefly discuss any limitations associated with this research scenario and the specific design.
