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. Scatter plots in statistics create the foundation for simple linear regression, where we take scatter plots and try to create a usable model using functions. In fact, all regression is doing is trying to draw a line through all of those dots!

There are just three steps to creating a scatter plot by hand.
Construct a Scatter plot: Steps
Sample question: create a scatter plot for the following data:
Step 1: Draw a graph. Label the x- and y- axis. Choose a range that includes the maximums and minimums from the given data. For example, our x-values go from 3 to 6.3, so a range from 3 to 7 would be appropriate.
