I know it may seem like I am being difficult, but I think it would depend on what we mean by “small” vs. “large.” We stated above 30 is the smallest sample size is representative of almost any population. This is a bit hard for me to wrap my brain around because similar to Richard is saying, I think it might depend on what size the population being assessing. If you are talking about the entire United States, 30 people may not seem to be a very good representation.

Unformatted text preview: However, it we are talking about a small town of under 10,000 people, maybe 30 would be a great sample size. This of course is just my opinion. The article below states a small sample size can only be used when the variable is normally distributed. The catch is you cannot test for the assumption of normal distribution is the sample size is too small. Therefore, it would appear bigger is always better.
