Statistic

A statistic is a characteristic of a sample. Generally, a statistic is used to estimate the value of a population parameter.

For instance, suppose we selected a random sample of 100 students from a school with 1000 students. The average height of the sampled students would be an example of a statistic. So would the average grade point average. In fact, any measurable characteristic of the sample would be an example of a statistic.
