Definitions:

Mean

The arithmetic average of a set of numbers, calculated by summing them and dividing by the number of numbers.

Area

A quantity expressing the two-dimensional size or extent of a shape or surface, typically measured in square units.

Variance

A measure of dispersion in a set of data points, calculated by taking the average of the squared differences from the mean.

Standard Deviation

A statistic that quantifies the dispersion or variability of a dataset, measuring the average distance between each data point and the mean.
