Population Variances

A measure of how data points in a population are spread out, indicating the variability of the entire population.

Confidence Interval Estimate

An interval estimate is a range of values used to estimate a population parameter, typically defined by two numbers between which a population parameter is said to lie with a certain level of confidence.
