For this assignment, again, it is beneficial that you keep the topic you would like to research for the capstone proposal in mind (My topic is the psychological causes to mothers killing their children). The capstone will require a literature review for your proposal, of which you may use articles obtained during this course.

1. Compare the two research designs. (two-group design and a factorial design)
2. Identify the independent variable(s), dependent variable, and any possible extraneous variable.
3. Identify main effects and interactions for the factorial design.
4. Explain if the study has a random sample and/or random assignment. Were there other limitations that were noticed?
