Scatter Plot with JMP

What is a Scatter Plot?

A scatter plot is a diagram to present the relationship between two variables of a data set. A scatterplot consists of a set of data points. On the scatterplot, a single observation is presented by a data point with its horizontal position equal to the value of one variable and its vertical position equal to the value of the other variable. A scatterplot helps us to understand:

  • Whether the two variables are related to each other or not
  • What the strength of their relationship
  • The shape of their relationship
  • The direction of their relationship
  • Whether outliers are present

How to Use JMP to Generate a Scatter Plot

Data File: “”

Steps to render a scatter plot in JMP:

  1. Click Analyze -> Fit Y by X
  2. Select MPG as the “Y, Response” and weight as the “X, Factor”
  3. Click OK

Model summary: The figure above is JMP’s output of the scatterplot data. You can immediately see the value of graphical displays of data. This information obtainable by viewing this output shows a relationship between weight and MPG. This scatterplot shows that the heavier the weight the lower the MPG value and vice versa.
