Definitions:

Linear Regression

A statistical method for modeling the relationship between a dependent variable and one or more independent variables using a linear equation.

Correlational Analysis

A statistical method used to determine the degree to which two variables are related.

Analysis Of Variance

A test for the difference between two or more means. A simple analysis of variance (or ANOVA) has only one independent variable, whereas a factorial analysis of variance tests the means of more than one independent variable. One-way analysis of variance looks for differences between the means of more than two groups.

Slope

The measure of the steepness or incline of a line, defined as the ratio of the vertical change to the horizontal change between two points.
