Scatterplots are used to display the relationship between two variables.
Suppose we have the following dataset that shows the weight and height of players on a basketball team:
The two variables in this dataset are height and weight. To make a scatterplot, we place the height along the x-axis and the weight along the y-axis. Each player is then represented as a dot on the scatterplot:
Scatterplots help us see the relationship (positive, negative, none) between two variables as well as the strength of that relationship (weak, strong).
Weak, positive relationship: As the variable on the x-axis increases, the variable on the y-axis increases as well. The dots are fairly spread out, which indicates a weak relationship.
Use the free Statology scatterplot generator to generate a scatterplot for a dataset simply by entering data values.
