Definitions:

Normal Distributions

A probability distribution that is symmetric about its mean, showing that near the mean there's a higher likelihood of occurrence, a foundational concept in statistics.

Skewed

Skewed data are data that are not symmetrically distributed, showing a longer tail on one side of the data distribution.

Standard Normal Distribution

A normal distribution with a mean of 0 and a standard deviation of 1, used in many statistical contexts as a reference for probability calculations.

Theoretical Distribution

A statistical distribution based on assumptions about a population, used as a model to understand or predict real-world phenomena.
