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, but it’s actually one of the least...
Because simple random sampling tends to produce unbiased samples that mirror the population, it’s excellent for analysts who need to use a sample to infer the properties of a population (i.e., inferential statistics). In a study, having a representative sample improves both itsinternal and ext...
