Survey sample size determination is defined as an empirical study, whose goal is to draw conclusions about a population from a sample. Sample size needs to be determined efficiently in order to obtain meaningful research insights. Read more about the formula to determine sample size and examples.... Sample size is a statistical concept that involves determining the number of observations or replicates (the repetition of an experimental condition used to estimate variability of a phenomenon) that should be included in a statistical sample. It is an important aspect of any empirical study requiring that inferences be made about a population based on a sample. Essentially, sample sizes are
