What is a sampling distribution of a sample and what can it be used for?
What will be an ideal response?
A sampling distribution of a sample statistic is a theoretical expression that describes the mean, variation, and shape of the distribution of an infinite number of occurrences of the statistic when calculated on samples of size N drawn independently and randomly from a population. It can be used as a statistical tool for calculating the probability that sample statistics fall within certain distances of the population parameter. The sample information cannot, of course, tell us exactly where within the range of values the population parameter lies. But it allows us to make an educated guess.
