Definitions:

Coefficient of Determination

A statistical measure, often denoted as R², that represents the proportion of the variance in the dependent variable that is predictable from the independent variable(s).

Coefficient of Correlation

A numerical metric that determines the intensity and course of a straight-line association between two variables that can be quantified.

Sample Coefficient

A measure that quantifies some kind of property or behavior, such as variability or correlation, from a sample of a population.

Correlation

Correlation refers to a statistical measure that indicates the extent to which two or more variables fluctuate together. A positive correlation indicates that as one variable increases, the other does too.
