ANOVA Article Critique

Read the article “Cognitive Effects of Risperidone in Children with Autism and Irritable Behavior,” and identify the research questions and/or hypotheses as they are stated. Consider the following questions: What are the variables (sample sizes, population, treatments, etc.)? How was the analysis of variance used in this article (and what type of ANOVA was used)?

Write a two- to three-page paper presenting the information listed below. In addition, provide a title page and reference page in APA style. Cite any references made to the article within the body of the paper in APA style. Your paper should begin with an introductory paragraph (including a thesis statement) and end with a concluding paragraph summarizing the major points made in the body of the paper and reaffirming the thesis.

The body of your paper must:

1.Determine what question(s) the authors are trying to answer by doing this research.
2.Determine the hypothesis being tested and the concepts that were applied in this process.
3.Evaluate the article and critique the statistical analysis employed in the study. Would you have included more and/or different variables? Explain your answer.
4.Examine the assumptions and limitations of the statistical study. What would you have done differently in this case? Explain your answer.
5.Identify how the authors applied statistical testing to the problem.
6.Interpret the findings of the author(s) using statistical concepts.

Access the The Critical Thinking Community website for tips on how to formulate your thoughts and discussion of these questions in a logical and meaningful manner.

The third assignment required that we critique the article.

Aman, M. G., Hollway, J. A., McDougle, C. J., Scahill, L., Tierney, E., McCracken, J. T., . . . Posey, D. J. (2008). Cognitive effects of risperidone in children with autism and irritable behavior.Journal of Child and Adolescent Psychopharmacology, 18(3), 227-36. doi:http://dx.doi.org/10.1089/cap.2007.0133. Retrieved from the ProQuest database.

In particular, we were concerned with the

1.Research question(s),

2.Hypotheses,

3.Statistical analysis,

4.Variables,

5.Assumptions,

6.Limitations, and

7.Interpretations.

As with all of the assignments, we expect that learners will make their submissions in APA format. The ability to critique articles is important as we proceed. Here are to key-word indicators that should be searched (Purugganan& Hewitt, n.d.).

•surprising

•unexpected

•in contrast with previous work

•has seldom been addressed

•we hypothesize that

•we propose

•we introduce

•we develop

•the data suggest

In reading an article, learners should base their evaluation on the numbers, tables and graphs that comprise the statistical analyses. For further insight on this topic, the succeeding websites are recommended:
