Definitions:

Regression Equation

A statistical method for estimating the relationships among variables, often used for predicting the value of a dependent variable based on the values of one or more independent variables.

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.
