My research question is”How has the COVID-19 pandemic affected existing racial inequalities?” I am using face-to-face surveys for this research. For the independent variable, I am focusing on diagnosing viruses and government and healthcare system requirements. For the dependent variable, I am focusing on finance between races, including economic inequality between races employment gap between races. I am using stratified sampling; the sampling frame can be the health insurance enrollment information.
Question: Evaluate your research design in terms of reliability, construct validity, internal validity, and external validity. Go over all four of these, discussing strengths and (potential) weaknesses. It is okay for there to be weaknesses—you do NOT need to justify them.
