This is a study of 18 people. Take that with a grain of salt, but also realize that many studies on people tend to have really small numbers of people.

- iopq 11y agoThat only matters if results differ between each person. If everyone has the same results, 18 people is plenty to prove that the results are the same for everyone. It depends on the sample variance and the number of people. If you have high sample variance, you need a higher N to make it less likely that you have a sampling error. If you have very low sample variance, just a few people is enough.

- iopq 11y agoWe actually DON'T know that. It could be every person gets almost the same result.
