Answer to Question #154198 in Statistics and Probability for Juergen

Question

Distinguish between a parameter and a statistic using relevant examples

Answer 1

A parameter describes the whole population, while statistic describes a part of the population.

For example, the average weight of adult men in the U.S. is a parameter with an exact value – but we don’t know it. The average weight of 100 randomly chosen U.S. adult men is statistic and it can be calculated.
