To prepare:
Review this week’s Learning Resources, focusing on how researchers find meaning in their data and generate sound conclusions. Pay particular attention to Table 2 in the article, “Study Design in Medical Research.”
Revisit the 5 articles that you identified in Part 2 of the Course Project. Select one to consider for the purpose of this Discussion.
Read sections of the chosen article where the data is presented, analyzed, and interpreted for meaning. What reasoning process did the researchers use to formulate their conclusions? What explanation did they give to support their conclusions? Were there any weaknesses in their analysis or conclusions?
Consider possible alternate conclusions that the researchers could have drawn based on their data.
Examine the findings that the article presents and consider how well they addressed the researcher’s initial question(s). What additional research could be done to build on these findings and gain a fuller understanding of the question?
Post an APA citation and brief summary of the research article that you selected. Describe the data and the results of any statistical tests or analyses presented in the article. Explain how the researchers formulated their conclusion, any weaknesses in their analysis or conclusions, and offer at least one alternate interpretation of their data. Propose at least one additional research study that could be done to further investigate this research topic.
