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 linear regression, where we take scatter plots and try to create a usable model using functions. In fact, all linear regression is doing is trying to draw a line through all of those dots!
If you want to construct a scatter plot by hand, read on for the steps. However, if you have access to some kind of technology (like Excel), it’s much easier! Follow a link to make a:
- SPSS Scatter plot
- Scatter plot in Minitab
- TI 89 Scatterplot
- Scatter plot in Microsoft Excel
- TI 83 Scatter plot
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.
