A value on a scale of one to a hundred that indicates the percent of a distribution that is equal to or below it.

Normal Curve

A bell-shaped curve that represents the distribution of many types of naturally occurring data; synonymous with Gaussian distribution.

Normal Random Variable

A variable that is distributed in a way that fits the normal (Gaussian) distribution, characterized by its mean and standard deviation.

Mean

The average of a set of numerical values, calculated by adding them together and dividing by the number of values.
