The process of finding an approximate value of some parameter—such as the mean (average)—of a population from random samples of the population.
It is the value of statistic that estimates the value of a parameter.
The sample standard deviation (s) is a point estimate of the population standard deviation (σ).
The sample mean (̄x) is a point estimate of the population mean, μ.
The sample variance (s2) is a point estimate of the population variance (σ2).
