Definitions:

Discrete Random Variables

Random variables that take on a countable number of distinct values.

Continuous Random Variables

Variables that can take on any values within a continuous range, as opposed to discrete variables that have specific, separate values.

Normal Distribution

It's a probability distribution where the frequency of data decreases as the distance from the mean increases, exhibiting symmetry about the mean.

Standard Deviation

A statistical measure that quantifies the dispersion or spread of a set of data points around their mean.
