WebOct 24, 2024 · When the population is finite or smaller, the sample size calculated by the said formula ( 9.1) needs adjustment as shown below: {n}_ {adj}= Nn/\left (N+n-1\right) (9.1.1) where n adj is the adjusted sample size, N is the finite population size, and n is the sample size calculated by the Cochran’s formula ( 9.1 ). WebThe steps for this procedure are illustrated above. 1.A random sample of size n is taken from a population of size N. 2.A "superpopulation" of size N is formed by making N n copies of the sample.
