Discuss the assumptions of the statistical test used

Question

Journal Article Homework

Complete this homework using the DAA template.

Step I: Locate a scholarly journal article in the Capella University Library, preferably in your career specialization, that reports quantitative statistics. Although the article does not have to be based on a true experiment, it should report either a factorial ANOVA, a repeated measures ANOVA, multiple regression, dummy coded regression, or chi square.

Step II: Write Step I of the DAA. Provide a context of the journal article. Include a definition of the specified variables and corresponding scales of measurement. Specify the sample size of the data set. If applicable, discuss why the journal article is relevant to your career specialization.

Step III: Write Step II of the DAA. Discuss the assumptions of the statistical test used in the journal article. If possible, identify information in the article that indicates how these assumptions were tested. If no information on assumptions is provided, consider this as a limitation of the reported study.

Step IV: Write Step III of the DAA. Specify a research question related to the journal article. Articulate the null hypothesis and alternative hypothesis. Specify the alpha level if it is provided in the article.

Step V: Write Step IV of the DAA. Report the results of the statistical test using proper guidelines. This includes the statistical notation (e.g., F, b coefficient, χ²), the degrees of freedom, the statistical value of F, b coefficient, χ², and the p^¬-value. Also report the effect size and interpretation if one is provided. Interpret the test statistic against the null hypothesis.

Step 6: Write Step V of the DAA. Discuss the conclusions of the statistical test as it relates to the research question. Conclude with an analysis of the strengths and limitations of the study reported in the journal article.
