Anova Tests and DAA

Analyze a journal article in your career specialization that reports one of these statistical tests: correlation, tests, and one-way analysis of variance (ANOVA). In a maximum of 600 words using the DAA Template, provide a summary of the research study, identify the variables, articulate the research question and hypotheses, interpret the test statistic, and provide conclusions as well as the strengths and limitations of the study.

Step 1: Write Section 1 of the DAA

  • Provide a brief summary of the journal article. You should not exceed the limit of 600 words. This is a situation where less is better.
  • Include a definition of the specified variables (predictor, outcome) and corresponding scales of measurement (nominal, continuous).
  • Specify the sample size of the data set.
  • Discuss why the journal article is relevant to your career specialization.

Step 2: 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 about how these assumptions were tested.
    • If no information on assumptions is provided, consider this as a limitation of the reported study.

Step 3: Write Section 3 of the DAA

  • Specify the research question from the journal article.
  • Articulate the null hypothesis and alternative hypothesis.

Step 4: Write Section 4 of the DAA

  • Report the results of the statistical test using proper APA guidelines. This includes:
    • The statistical notation (such as rt, or F).
    • The degrees of freedom.
    • The statistical value of rt, or F, and the p value.
  • Report the effect size and interpretation if one is provided.
  • Interpret the test statistic with regard to the null hypothesis.

Step 5: 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.
