Designing Quantitative Research

T​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​he assignment for Week 6 is to write an annotation for a quantitative, peer-reviewed journal research article. An annotation must contain 3 paragraphs. Please use the template provided (copy attached) and include only one paragraph for each part of the annotation. Summary: This is similar to an abstract and written in past tense. Do not copy the abstract. Each summary should be written in your own words. Analysis: Focus on the strengths of the article or the study. Here you can be a critic; consider using the checklists from previous discussions to guide your analysis. Application: How can this study be informative or applied to a situation within your discipline. Please be sure to read the assignment carefully, read all Week 6 resources fully, and use the format provided in the sample annotated bibliography. Check your work to ensure you have fully responded to all parts of assignments and that you have used a scholarly writing approach. Attached is a sample copy of an annotated bibliography. Please follow the format. Discussion: Designing Quantitative Research Researchers consider validity and reliability with each new study they design. This is because validity and reliability are not fixed but rather reflect a particular study’s unique variables, research design, instruments, and participants. In the context of research design, two types of validity​‌‍‍‍‌‍‍‌‍‌‌‍‍‍‌‍‌‌‌‍​, which speak to the quality of different features of the research process, are considered: internal validity and external validity. Assuming that the findings of a research study are internally valid—i.e., the researcher has used controls to determine that the outcome is indeed due to manipulation of the independent variable or the treatment—external validity refers to the extent to which the findings can be generalized from the sample to the population or to other settings and groups. Reliability refers to the replicability of the findings. For this Discussion, you will consider threats to internal and external validity in quantitative research and the strategies used to mitigate these threats. You will also consider the ethical implications of designing quantitative research. With these thoughts in mind: By Day 4 Post an explanation of a threat to internal validity and a threat to external validity in quantitative research. Next, explain a strategy to mitigate each of these threats. Then, identify a potential ethical issue in quantitative research and explain how it might influence design decisions. Finally, explain what it means for a research topic to be amenable to scientific study using a quantitative approach.
