How to Construct a Scatter Plot
A scatter plot gives you a visual idea of what is happening with your data. Scatter plots in statistics create the foundation for linear regression, where we take scatter plots and try to create a usable model using functions. There are just three steps to creating a scatter plot.
Sample question: create a scatter plot for the following data:
| x | y |
|---|---|
| 3 | 25 |
| 4.1 | 25 |
| 5 | 30 |
| 6 | 29 |
| 6.1 | 42 |
| 6.3 | 46 |
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.
Step 2: Draw the first point on the graph. Our first point is (3,25).
Step 3:. Draw the remaining points on the graph.
Feel like cheating at statistics?
