• Review the Article Critique Assignment Guide in the Walden Library, listed in the Week 2 Learning Resources.
• Search the Walden Library for a quantitative article that applies factorial analysis of variance. Note that sometimes these are referred to as “two-way ANOVAs.”

The Assignment

Write a 2- to 3-page critique of the research you found in the Walden Library that includes responses to the following prompts:

• Why did the authors select factorial ANOVA in the research?
• Do you think this test was the most appropriate choice? Why or why not?
• Did the authors display the results in a figure or table?
• Does the results table stand alone? In other words, are you able to interpret the study from it? Why or why not?

  1. Introduction

  Begin your critique by introducing the article you’ve selected from the Walden Library. Provide the full citation in APA format and briefly summarize the study’s purpose, research questions, and hypotheses.

  ---

  2. Reason for Selecting Factorial ANOVA

  Identify and discuss why the authors chose to use a factorial ANOVA (also known as a two-way ANOVA) in their research.

  • Definition: Factorial ANOVA is a statistical test used to examine the effects of two or more independent variables on a dependent variable simultaneously.​

  • Application in the Study: Explain how the study’s design involved multiple independent variables and why analyzing their combined effects was necessary.​

  • Example: If the study investigated the impact of teaching methods and student gender on academic performance, a factorial ANOVA would be appropriate to assess both main effects and their interaction.​

  ---

  3. Appropriateness of the Test Choice

  Evaluate whether factorial ANOVA was the most suitable statistical test for the study.

  • Justification: Discuss whether the study’s design and data met the assumptions required for factorial ANOVA, such as:​

    • Independence of observations​

    • Normality of the dependent variable within groups​ScholarWorks

    • Homogeneity of variances​

  • Alternative Methods: Consider if other statistical tests could have been more appropriate and explain why or why not.​

  ---

  4. Presentation of Results

  Analyze how the authors presented their findings.

  • Use of Figures or Tables: Note whether the results were displayed using tables, figures, or both.​

  • Clarity and Completeness: Assess whether these visual aids were clearly labeled and included all necessary information, such as means, standard deviations, F-values, degrees of freedom, and p-values.​

  ---

  5. Interpretation of the Results Table

  Determine if the results table is self-explanatory and allows for independent interpretation.

  • Stand-Alone Quality: Evaluate whether a reader could understand the study’s outcomes solely based on the table, without referring to the main text.​

  • Suggestions for Improvement: If the table lacks clarity, suggest ways it could be enhanced to better convey the results.​

  ---

  6. Conclusion

  Summarize your critique by highlighting the strengths and weaknesses of the article’s use of factorial ANOVA. Reflect on how this analysis contributes to the field and any implications for future research.

  ---

  References

  Include any additional sources you consulted to support your critique, formatted according to APA guidelines.
