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.
