Question

Quizplus · Accepted Answer

A sample statistic is a value calculated from a sample of data, such as the sample mean. It is not a population parameter, which would be a fixed value describing the entire population. The mean deviation is a measure of dispersion, and the central limit theorem describes the tendency for sample means to approach a normal distribution as sample size increases. Therefore, the best choice is A, as it specifically refers to a value calculated from a sample.
