Definitions:

Independent Variable

The variable in an experiment that is manipulated or changed by the researcher to observe its effects on the dependent variable.

SSE

Stands for Sum of Squared Errors, a measure used in statistics to indicate the difference between the observed and predicted values.

Coefficient Of Determination

A statistical measure, often denoted as R^2, that illustrates the proportion of variance for a dependent variable that's explained by an independent variable or variables in a regression model.

Y-intercept

The point where a line crosses the Y-axis of a graph.
