Definitions:

Normal Random Variable

A normal random variable is a variable whose values are distributed according to the normal distribution, characterized by its mean and standard deviation.

Standard Deviation

A statistic that measures the dispersion or variability of a dataset relative to its mean, indicating how spread out the numbers are.

Normally Distributed

Refers to a type of distribution where the data points are symmetrically distributed around the mean, with most observations clustering around the central peak and the probabilities for values further from the mean tapering off equally in both directions.

Mean

The mean of a collection of numbers, determined by dividing their total sum by the count of the numbers.
