If R² is greater than .80, there is a strong relationship between the two data sets. R² close to 1.0 means a perfect fit.
Example of an Excel Scatter Plot Diagram Created by QI Macros
Scatter Plot Diagrams are used to evaluate the correlation or cause-effect relationship (if any) between two variables (e.g., speed and gas consumption in a vehicle).
When you think there's a cause-effect link between two indicators (e.g., calories consumed and weight gain) then you can use the scatter plot to prove or disprove it. If the points are tightly clustered along the trend line, then there's probably a strong correlation. If it looks more like a shotgun blast, there is no correlation.

Scatter Plot Diagrams can be made manually or in Excel. However, you have to find the right chart to get a trend line and Excel will not calculate the R² correlation of determination (square of the correlation coefficient) for you.
Use a Scatter Plot Maker like QI Macros for Excel to save time and get the calculations right.
