Explanation:
Detailed explanation-1: -The minimum sample size is 100 Most statisticians agree that the minimum sample size to get any kind of meaningful result is 100. If your population is less than 100 then you really need to survey all of them.

This type of sampling is ideal for more controlled studies where human bias in the selection of the sample is intolerable.
