Key Concepts

Parameter

A parameter is a numerical measure that describes a characteristic of an entire population. It is a fixed value that is generally unknown because it is impractical or impossible to measure an entire population, yet it is the value that statisticians aim to estimate using sample data.

Statistic

A statistic is a numerical measure that describes a characteristic of a sample drawn from the population. It is calculated using the data from the sample and is used to make inferences about the corresponding population parameter, acknowledging that the value can vary from sample to sample.
