WebbSince we have a population of 185 and 185 is a three digit number, we need to use the first three digits of the numbers listed on the chart. We close our eyes and randomly point to a spot on the chart. For this example, we will assume that we selected 20631 in the first column. We interpret that number as 206 (first three digits). WebbIn statistics, a simple random sample (or SRS) is a subset of individuals (a sample) chosen from a larger set (a population) in which a subset of individuals are chosen randomly, all with the same probability.It is a process of selecting a sample in a random way.
