Selection of sample in research
WebThe 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. A good maximum sample size is usually 10% as long as it does not exceed 1000 WebIt refers to a sample that has been selected using random selection so that each unit in the population has a known chance of being selected.
