Sampling and Measurement When researchers conduct a quantitative research study, they must ensure that the instruments and sample population they use mesh well with the study’ s goals and objectives so that they will produce valid and reliable results. To prepare for this Discussion, review the Learning Resources while considering the following: ?What makes a research study valid and reliable? ?What issues related to sampling (e.g., size and selection of sample data) do researchers need to keep in mind? What are the limitations of sampling in conducting research? ?What considerations need to be taken into account regarding measurement? Then, with these thoughts in mind, critique the articles “Assessing the Performance of Freestanding Hospitals” and “A National Study of Efficiency for Dialysis Centers” in this week’s Learning Resources. What are the strengths and weaknesses of each of the studies? By Day 4, post a comprehensive response to the following: ?Describe the strengths and weaknesses of each of the studies described in the articles, as well as the sample design(s). Be sure that your analysis takes into account sampling and measurement. ?Propose potential remedies to address the weaknesses of each study.
