Journal Article Assignment- Advanced Inferincial Statistics
Complete this assignment using the DAA template.
Step 1. 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 2. Write Section 1 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 3. Write Section 2 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 4. Write Section 3 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 5. Write section 4 of the DAA. Report the
results of the statistical test using proper APA 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 Section 5 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.
