Question

The population variance is also called.

Answer 1

Population variance (σ2) tells us how data points in a specific population are spread out. It is the average of the distances from each data point in the population to the mean, squared. ... μ is the population mean.

Answer 2

The population variance is also called sigma squared.

• A type of variance called population variance is used to determine the variability of population data in relation to the mean.
• The population variance (σ²) describes how data points in a given population are distributed.

• The population size is N, and the data points are $x_{i}$ the population's average.
• It is the average of the distances between each data point in the population and the mean, squared.
