You will begin to examine quantitative literature, determine level of evidence, quality of study methods, biases, strengths & limitations, and all elements that affect the quality of a study. You will continue the articles series to learn the processes of evidence appraisal (articles are posted in Readings.
Quantitative Research Analysis
Critical analysis is dependent on the type of research conducted. Utilize a mechanism for evaluating the worth of a study. Although an RCT study has long been considered the “gold standard” of quantitative research, RCTs do not always provide depth and variety of response to a given research question. In fact, meta-analyses and systematic reviews of RCTs provide the highest level of research evidence and provide much information when evaluating research for evidence-based practice changes. Not all systematic reviews, meta-analyses or RCTs are of high quality. You will learn to look at this research with a critical eye in evaluating the evidence for use in practice.
You will also create an evaluation table for the article you use in your assignment. An evaluation template is provided for you. It is also recommended that you view the video provided about how to develop an evaluation table.
Objectives
Describe how different quantitative research designs best answer different types of clinical questions.
Explain the four phases of critical appraisal.
List the three key questions to ask of all studies.
Explain the markers of good research for different types of quantitative research.
Discuss the role of interpreted statistics in clinical decision making.
Discuss how recommendations for practice come from a body of evidence.
Critique a randomized clinical trail article using the information learned from chapters 4 & 5.
Readings
Chapters 4 & 5 in textbook.
Appendix B for the RCT rapid critical Appraisal (RCA) questions for randomized clinical trials.

The purpose of this assignment is to assist the DNP student in taking a critical look at a quantitative study and evaluating the quality of the research done for recommendation as use of evidence for practice/policy change.
Assignment
Obtain an original research article that is a randomized control trial (RCT) in a reputable journal. The RCT should be relevant to your DNP project. Use the RCT Rapid Critical Checklist (RCA) in Appendix B to critique your article
Use short descriptors when answering questions. ****Do not copy/paste the long questions from Appendix B and give one sentence answers. Your critique must provide the why/how? Specifically describe why you think the article does/does not meet each area of evaluation. Faculty are looking for in-depth evaluation of the evidence at the doctoral level. For example, it is not acceptable to simply mention that the sampling was adequate. Detail how or why the sample was adequate, describe the inclusion and exclusion criteria, sample size calculation, power calculations, etc.
The critique is the main body of your paper. Use the grading rubric and RCT Rapid Critical Checklist (RCA) as a guide to structuring your paper.
Unit 2/Chapter 5 walks you through the evaluation of a quantitative article. Please read/review this information before beginning the assignment.
Identify applicability of the study to your patient population and practice area.
Summarize evaluation and provide recommendations for use as evidence. Remember that the point of this paper is a critique/appraisal of the study. Summarize the mains points of your critique and give your overall conclusion for the quality of the study you appraised.
Place article in an evaluation table. Read chapter 5 for information regarding evaluation tables. A template for the evaluation table can be found in the Canvas module
Use APA format with level one headings (Please do not copy/paste the long RCA questions for headings) – For example, for the question Are the Results Valid? Use the heading Validity. Professional writing is expected. Make sure that tables are APA formatted. Table titles need to be in APA format: Do not use “Evidence Table” as your title. The title should reflect what you are presenting in the table. See “General Guidance on Tables and Figures” in your APA textbook. Upload both the article used for the assignment and the assignment into the Canvas dropbox
