Simple random sampling computation

WebbA simple random sample (SRS) is the most basic probabilistic option used for creating a sample from a population. Each SRS is made of individuals drawn from a larger population (represented by the variable N ), completely at random. As a result, said individuals have an equal chance of being selected throughout the sampling process. Webb27 juni 2007 · Abstract.
