Report Abuse. POPULATION PARAMETER(p) is a value used to represent a certain QUANTIFIABLE characteristic of a population. This is like the mean or variance of a population and often these values are unknown, and are estimated using sample data.
A parameter is any number calculated from a population. A statistic is any number calculated from a sample. It is important to remember that we are often concerned about the population and the calculated parameters associated with that population. However, we usually do not know or can not obtain these values, so we rely on sampling and statistics to provide us with inferences about the population.
