In mathematics, the extent of a two-dimensional surface within a boundary, measured in square units.

Probability Density

A function that describes the relative likelihood for a continuous random variable to occur at a specific point.

Normally Distributed

A statistical distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Standard Normal

A normal distribution with a mean of zero and a standard deviation of one, serving as the basis for z-score calculations in statistics.
