To choose a random sample from your data stored in an Excel workbook, you must first assign random numbers to each row. The RAND function can be used to generate random numbers for a cell or group of cells. Once
“a random sample of 100 households” It isn’t true that a random sample is chosen “without method of conscious decision.” Simple random sampling is one way to choose a random sample. What is a Simple Random Sample? A simple random sample is often mentioned inelementary statisticsclasses,...
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 random sampling (SRS) with replacement (SRSWR) and most of his successors followed it...
