S.L. Warner, the pioneer in research on randomized responses (RRs) to gather and analyze sensitive and stigmatizing data, started specifically with samples selected exclusively by the simplest scheme of simple
How to Perform Simple Random Sampling: Example A larger population might be “All people who have hadstrokesin the United States.” That list of participants would be extremely hard to obtain. Where would you get such a list in the first place? You could contact individual hospitals (of whic...
