Assignment 2: Discussion—Should You Believe a Statistical Study?

We are bombarded by statistical information from a wide variety of sources every day. A lot of the statistical research performed in the world is conducted with a great deal of integrity, validity, and reliability. However, many statistical studies are—intentionally or unintentionally—plagued by bias.

As a member of society, and as a consumer, it is prudent to develop the skills that are necessary to critically examine reported statistical claims.

Review this module’s readings to better understand the credibility of statistical studies. Next, conduct an Internet search to find a study whose statistical results have been published in a public forum. Then, apply the guidelines to critically analyze the content, design, and reported results of a statistical study. Do the following to complete this assignment:

  • What was the goal, population, and type of study?
  • Who conducted the study?
  • Is there any bias in the study or the samples used? If so, describe.
  • Are there any problems in defining or measuring the variables of interest? If so, describe.
  • Are there any confounding variables? If so, describe.
  • Are the results presented fairly? How did you make that determination?
  • Is the study’s conclusion reasonable? How did you make that determination?
  • Are the results practical? How did you make that determination?

Write your initial response in a minimum of 200 words. Apply APA standards to citation of sources.

By Saturday, February 21, 2015, post your response to the appropriate Discussion Area. Through Wednesday, February 25, 2015, review the postings of your peers and respond to at least two of them. Consider commenting on the following:

  • Do you agree with your peers’ identification of bias in the study? Are there other sources of bias to consider?
  • Based upon the peers’ analysis, and your review, would you accept the conclusion of this study? Why or why not?
