A parameter describes which set in statistics?

• A. Population
• B. Repeated measures
• C. Sample
• D. None

Answer: (A)

A parameter describes the population. In statistics, a parameter is a numerical value that summarizes a characteristic of the entire group of interest—the population—such as the population mean, population variance, or population proportion. It is considered fixed, even though we usually don’t know its exact value. A statistic, on the other hand, comes from a sample and can vary from one sample to another, serving as an estimate of the population parameter. Describing repeated measures pertains to collecting multiple observations from the same unit, not to describing the population as a whole.
