Definitions:

Outlier

An observation in a data set that is distant from other observations, often indicating a measurement error or a unique phenomenon.

Mode

The most prevalent figure found in a group of data points.

Central Tendency

A measure that represents the center or typical value in a dataset, commonly understood through mean, median, and mode.

Qualitative Data

Non-numerical information that describes qualities or characteristics of what is being studied.
