Research Proposal Part II
100 points possible
Method/Design:
State your population of interest, how and whom you will sample, and the basic study design. Provide information on proposed statistical analyses. This part should also be about 5 pages.
You will use the Differential Research Method below; I have attached a Sample Paper that will also help with this assignment.
You can use my Scholarly Peer Review articles that I attached and sent you already to help with this assignment or get your own; just include the reference please.

Differential research compares two or more groups that differ on preexisting variables. Qualitative dimensions (e.g., gender, political party affiliation, or psychiatric diagnosis) or quantitative dimensions (e.g., the participants age or number of years of education) can define the groups.
Whether defined qualitatively or quantitatively, the group differences existed before the researcher conducted the study. The researcher measures these differences and assigns participants to groups based on them. This classification variable is the independent variable, and the behaviors measured in the different groups are the dependent variables. Independent variables in differential research are non-manipulated independent variables.
Differential research involves measuring variables but not manipulating them and is thus conceptually similar to correlational research. This similarity means that we use the same general principles in interpreting the results from each of these approaches. Specifically, we avoid drawing causal conclusions from either differential or correlational research studies.
Note that there is a structural similarity between differential and experimental research: both utilize different groups defined by an independent variable, and the researcher measures a dependent variable on all participants in each group. Given that similarity, the same statistical procedures are used to evaluate the data from these two approaches. Thus, differential research is similar to both correlational and experimental research. Nevertheless, this similarity between differential and experimental research does not override the admonition that one cannot determine causation from differential research.
