Weekly Discussion 2

Article Critique: Chi-Square Test

The readings for this week focus on the concepts of z tests, t tests,  and Chi-Square tests. 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:

• Apostolou, M. (2010). Parental choice: What parents want in a  son-in-law and a daughter-in-law across 67 pre-industrial societies.  British Journal of Psychology, 101, 695-704. doi:  10.1348/000712609X480634

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

• Research question – State the research question for the study.
• Hypotheses – Provide 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.
