Construct a Scatter plot: Overview
A scatter plot gives you a visual idea of what is happening with your data. Scatter plots are similar to line graphs. The only difference is a line graph has a continuous line while a scatter plot has a series of dots.

In fact, all regression is doing is trying to draw a line through all of those dots!
