Question

Quizplus · Accepted Answer

Mean, variance, and standard deviation are all measures of central tendency and variability that describe a population. Thus, they are population parameters. Sample statistics, on the other hand, are estimates of population parameters that are calculated using data from a sample of the population. Population Z scores and regressed standardized scores are not relevant to this concept.
