Everyone mentions simple random sampling, but few use this method for populationbased surveys. Rapid surveys are no exception, since they too use a more complex sampling scheme. So why should we be concerned with simple random sampling? The main reason is to learn the theory of sampling. Simple random sampling is the basic selection process of sampling and is easiest to understand.

Often, these studies consist of detecting whether some binary sequence has the properties of a bernoulli random variable. From the re sults of these studies, we can conclude experimental subjects hold the Law of Small Numbers (Tversky & Kahneman…
