Critical Proposal For Critical Appraisal

Quantitative Research Report Critical Appraisal-Dietary Vitamin K Guidance Researchers use quantitative research approach when they are interested in learning the relationships among variables. A variable is something that is various, including blood pressure, weights, and pain levels. It can be categorized in a different level of measurement: nominal, ordinal, interval, and ratio measurement (Polit & Beck, 2012). Depending on the numbers of variables and groups in a study, researchers can choose a corresponding research design and statistical tests. Experimental, also called a randomized controlled trial, and non-experimental (observation) are two main research designs for a quantitative research study. In a medical field, experimental research

There are some sub-groups under introduction, method, results, discussion, and global issues. Firstly, researchers should explicitly state hypotheses/research questions, the statement of the problem, literature review, and conceptual/theoretical framework of a quantitative research study in the section of introduction. Secondly, method should be followed by introduction and includes: protection of participants’ rights, research design, population and sample, data collection and measurement, and procedures. Thirdly, after researchers explain the method, then followed by results. Results of a study should include data analysis and findings. Fourthly, researchers should also interpret the findings and implications or recommendations of a study. The lastly, the global issues are stated at the end of an appraisal report, which should include the discussion about presentation, researcher credibility, and summary assessment of a quantitative research study. The quantitative research study, Dietary Vitamin K Guidance: an Effective Strategy for Stable Control of Oral Anticoagulation, will be critiqued below, based on those essential elements.

Title

The tile of the research study, Dietary Vitamin K Guidance: an Effective Strategy for Stable Control of Oral Anticoagulation, was well written and explicitly suggested key variables: whether or not vitamin K dietary guidance was an effective strategy to adjust oral anticoagulation. However, the title had some grammatical errors. The letter, “a” followed by a semicolon should be capitalized. In addition, the question mark at the end of the title should be eliminated. The title did not indicate whether or not this is a quantitative research
