When we sample less than 5% of the population,the finite population correction factor;fpc = $\sqrt { ( N - n ) / ( N - 1 ) }$
,is used to modify the formula for the standard error of the sample mean.

Quizplus · Accepted Answer

The finite population correction factor is used when sampling more than 5% of the population, not less.

When We Sample Less Than 5% of the Population,the Finite (N−n)/(N−1)\sqrt { ( N - n ) / ( N - 1 ) }(N−n)/(N−1)​
