CONCLUSION
Let's see if our independent variable (IV) affects
the dependent variable (DV).
An Independent Variable is like age, gender or height while a
Dependent Variable is whether you prefer Elvis Presley or Elvis Costello.

Scatter Plots
Scatter plots are a great first step for assessing the strength and direction of a relationship between two continuous variables. Sometimes the relationships are really obvious, but sometimes they are not. These scatter plots do not show a correlation. The red line indicates the residual line, what is left over of Y after we've accounted for X. This line indicates the best line for the closest fit to the data dots.

Linear Regressions
Linear regression models are used to show or predict the relationship between two variables or factors. The factor that is being predicted is called the dependent variable (Viable Third Party). The factors used to predict the value of the dependent variable are called the independent variables (Party Choice, Gender, Age, etc.). In linear regression, each observation consists of two values. One value is for the dependent variable and one value is for the independent variable. In this case we are showing multiple independent variables, while holding confounding variables constant, this is known as a Multiple Regression.
