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.

Detailed explanation-2: -The experimental methodologies require at least 15 participants according to Cohen et al. (2007:102), and there should be at least 15 participants in control and experimental groups for comparison according to Gall et al. (1996). These references can be taken by researchers using small sample size.

Detailed explanation-3: -Some examples of common rules of thumb are: Studies should involve sample sizes of at least 100 in each key group of interest. For example, if you are doing an AB test, then you would typically want a minimum sample size of 200, with 100 in each group.

Detailed explanation-4: -Sample size refers to the number of participants or observations included in a study. This number is usually represented by n. The size of a sample influences two statistical properties: 1) the precision of our estimates and 2) the power of the study to draw conclusions.
