Case-Study: Reliability and Validity
Week 3 discussion DQ 1 When you develop a research project, you need to have a reliable and valid method of measurement in your study. Using your anticipated research proposal, how will you address the issues of reliability and validity? What concerns do you have over reliability and validity in your study and how will you overcome these concerns? Next, read two of your classmates’ posts and analyze how they addressed reliability and validity in their studies. Do you have any recommendations for improving reliability and validity? DQ 2 Appropriate sampling is a critical component in developing a good research project. Using your approved research questions and research topic, explain your anticipated sampling method and why this is appropriate for your research proposal. What is your sample size? Next, read and review two of your classmates’ posts and analyze their sampling approach. Are their sampling approaches appropriate? Why or why not?
