Quantitative Research

Write a fully developed and detailed APA essay addressing each of the following points/questions. There is no required word count; be sure to completely answer all the questions for each question in detail. Separate each section in your paper with a clear heading that allows your professor to know which bullet you are addressing in that section of your paper. Support your ideas with at least one (1) source using citations in your essay. Make sure to cite using the APA writing style for the essay. The cover page and reference page are required. Review the rubric criteria for this assignment.

Conduct a literature search to select a quantitative research study related to the problem identified in Module 1 and conduct an initial critical appraisal. Respond to the overview questions for the critical appraisal of quantitative studies, including:

• Is this quantitative research report a case study, case control study, cohort study, randomized control trial or systematic review?
• Where does the study fall in the hierarchy of evidence in terms of reliability and risk of bias?
• Why was the study done? (Define the problem and purpose.)
• Were the steps of the study clearly identified?
• What was the sample size?
• Are the measurements of major variables reliable and valid? Explain.
• How were the data analyzed?
• Were there any untoward events during the conduct of the study?
• How do the results fit with previous research in the area? (This may be reflected in the literature review.)
• What does this research mean to clinical practice?

Additionally, be sure to include the rapid appraisal questions for the specific research design of the quantitative study that you have chosen. These can be found in Chapter 5 of the textbook (Melnyk and Fineout-Overholt, 2015).

This critical appraisal should be written in complete sentences (not just a numbered list) using APA format.

Provide a reference for the article according to APA format and a copy of the article.
