Scatter Plot with Minitab
What is a Scatter Plot with Minitab?
A scatter plot in Minitab is a diagram that presents the relationship between two variables in a data set. A scatter plot consists of a set of data points. In a scatter plot, each observation is represented as 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 scatter plot 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 Generate a Scatter Plot with Minitab
Data File: “Scatter Plot” tab in “Sample Data.xlsx”
Steps to render a Scatterplot in Minitab:
- Click Graph → Scatterplot.
- A new window named “Scatterplots” pops up.
- Leaving “Simple” selected, click “OK”
A new window “Scatterplot– Simple” pops up. - Select “MPG” as the “Y variables.”
- Select “weight” as the “X variables.”
- Click “OK.”
- The scatter plot appears in the new window.
Model summary: The figure above is Minitab’s output of the scatterplot data. You can immediately see the value of data visualizations. This information, available from the output, shows a relationship between weight and MPG. This scatterplot shows that higher weight is associated with lower MPG, and vice versa.
