**point estimation**, in statistics, the process of finding an approximate value of some parameter—such as the mean (average)—of a population from random samples of the population.In statistics,

**point estimation**involves the use of sample data to**calculate**a single value (known as a**point****estimate**since it identifies a**point**in some parameter space) which is to serve as a "best guess" or "best**estimate**" of an unknown population parameter (for example, the population mean ).People also ask

**a Point Estimate**in Statistics? Often in statistics we’re interested in measuring population parameters – numbers that describe some characteristic of an entire population. Two of the most common population parameters are: 1. Population mean: the mean value of some variable in a population (e.g. the mean height of males in a certain city)May 5, 2020 ·
