Question

Quizplus · Accepted Answer

When individuals in the population are very similar to one another on the dependent variable, small samples can be as adequate as larger samples. This is because the smaller sample will capture the overall variability of the population, and the results will be representative. With very similar individuals, the risk of missing important subgroups or hidden variability is small.
