Definitions:

Height

The measurement of an object or point in relation to ground level or a base level, typically considered vertical distance.

Coefficient Of Determination

A statistical measure that assesses the proportion of the variance in the dependent variable that is predictable from the independent variable(s), commonly represented as R^2.

Variation

The measure of the spread or dispersion of a set of values.

Standard Error Of Estimate

A measure of the accuracy of predictions made with a regression line, specifically, it estimates the standard deviation of the error term.
