Scatter Plot using JMP

What is a Scatter Plot?

A scatter plot is a diagram to present the relationship between two data set variables. 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 is 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: “ScatterPlot.jmp”

Steps to render a scatter plot in JMP:

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