However, there may be more than one independent variable that affect the dependent variable. In this case we utilize the multiple regression method. Review the following videos:

Describe the objective in using simple and or multiple regression models.
What does the ANOVA (analysis of variance) table demonstrate?

Define the coefficient of determination (r-square) and interpret its results (i.e. weak or strong relationship).

How do we determine whether our model determines a significant relationship between our variables? Evaluate at least two methods to arrive at your conclusions.
Describe the statistical inferences one can make utilizing the results of a regression model.
