A researcher wants to know whether there is a relationship between age and racial prejudice. She designs a survey in which respondents are asked to rate their prejudice against six different ethnic groups. She distributes the survey to over 500 people of various ages who are approached at a shopping mall in a low-income, inner-city neighborhood. What are the methodological flaws in this study?

Solution

This survey implements Convenience sampling and thus suffers from selection bias as this survey takes only people arriving at one shopping mall that too in low income inner city neighborhood.
