Scatter Plot with Minitab

What is a Scatter Plot with Minitab?

A scatter plot with Minitab is a diagram to present the relationship between two variables of a data set. A scatter plot consists of a set of data points. On the scatter plot, 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 scatter plot 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
