Definitions:

Normally Distributed

Refers to a distribution that follows the normal (bell-curve) shape, characterized by a symmetric shape around the mean, indicating random variables with equal mean, median, and mode.

Spearman Rank

A nonparametric measure of rank correlation that assesses how well the relationship between two variables can be described using a monotonic function.

Ordinal Variables

Variables that represent categories with a natural order or ranking among them, though the intervals between the rankings may not be equal.

Interval Variables

Variables that have measurable distances between values but no true zero point, allowing for the calculation of meaningful differences.
