Scatter
Abstract
Use a scatter plot to show correlation between two variables.
A scatter plot uses coordinates to show values for two (or more) variables in a data set.
Each point represents one value, where the position on the horizontal and vertical axis are determined by two variables.
When to use this tool
Use when you want to show correlation between two variables. Use caution when showing correlation - remember, correlation does not equal causation. Good for exploring relationships rather than drawing conclusions.
Example
You could use a scatter plot to show the link between someone's lung capacity (variable one) and how long they can hold their breath (variable two).
