GuidelineStatement of the scientific hypothesis with identification of the criterion and predictor and covariate variables and if applicable coding rules. Writing suggestion, although your program script may refer to variables by acronym or abbreviated name, use of this shortened name is generally unacceptable in APA unless appropriately introduced. • Statement of the statistical test(s). • Statement of the results of the statistical test(s) with reference to a table or figure. • A general conclusion statement that summarizes the full analysis. • General confirmation to APA writing guidelines.
Randomized Factorial Between Subjects DesignRead the data set .dat and test the hypotheses that there are differences in mean stress scores between different sex and ethnic groups (W, AA, H). Make sure to test for the interaction and conduct appropriate post-hoc comparisons. Turn-in a write-up conforming to the APA editorial style that includes answers to the following questions: a) statements of your research question/hypotheses that identifies the variables under study (IVs and DV), b) a short description of the sample, e.g., include a summary table of descriptive statistics; c) evaluation of the assumptions underlying the statistical tests, d) a summarization of the test statistic findings, e) presentation of any relevant post hoc test findings and f) your conclusion regarding your research question/hypotheses. Support your conclusions with a tentative interpretation of the findings.
Extra Credit (1 pt). Select and read a primary source from a peer-reviewed journal no older than 2012 in a research area of your interest that presents an analysis of a randomized factorial between-subject design (2- or 3-Between). Turn-in a paragraph summary conforming to APA style (no more than one paragraph, 200-word maximum) which includes answers to the following questions: (a) What was the general problem under study, (b) specifically what research question/hypothesis were the researchers testing with the specified analysis (i.e., between-subject factorial design), (c) what were the variables under study (what were the IVs and DV), (d) did the analysis relate to the general problem the researchers were investigating, (e) what were the findings (primary and post hoc) of the specific analysis, and f) did the researchers provide any evidence that the statistical assumptions were evaluated/met? Be sure to include an APA reference for the article. This should be included at the end of your assignment document, not a separate document upload.
