Repeated Measures ANOVA

Weekly Discussion 2

Article Critique: Repeated Measures ANOVA

The readings for this week focus on the concepts of basic ANOVAs,  including one-way and repeated measures ANOVA. In this discussion we  will apply those concepts to the review and critique of a research  article. For information on how to critique a research article, see the  Coughlan et al. (2007) and UIS (n.d.) guides listed in the Required  Readings for this week.

Read the following article.

• Lee, M., & Johnson, T. E. (2008). Understanding the effects of  team cognition associated with complex engineering tasks: Dynamics of  shared mental models, Task-SMM, and Team-SMM. Performance Improvement  Quarterly, 21 (3), 73-95. doi: 10.1002/piq.20032

In the body of your posting, include an overview of the following topics:

• Research question – List the research question for the study.
• Hypotheses – List the statistical notation and written explanations for the null and alternative hypotheses for the study.
• Methods and Study Design – Describe the basic methods used, including the variables, sampling methods, data collection, etc.
• Data Analysis – Summarize the statistical tests conducted, the  results obtained from each test, and conclusions regarding the  hypotheses.
• Critique – Critique the results of the study, paying specific  attention to the appropriateness of the analyses conducted, any biases  or assumptions that were made, practical significance of the results,  and recommendations for improving upon the study (methods or analyses). •  Summary – Provide a brief summary of the study’s findings in 2-3  sentences. Do not use any numbers or statistical terms, but provide a  review that would make sense to someone who has not studied research  methods or statistics.
