Factor Analysis

A statistical method used to describe variability among observed, correlated variables in terms of potentially lower number of unobserved variables, called factors.

Variables

Elements, features, or factors that are liable to vary or change.

Correlations

Statistical measures that describe the extent to which two variables change together, but not necessarily indicating that one causes the other.
