Let's take hypothetical data presenting blood pressure and high fat intake (less than 3 grams of total fat per serving) or low fat intake (less than 1 gram of saturated fat) of an individual.

Using the Minitab statistical procedure:

  • Calculate a one-way ANOVA to test the null hypothesis that the mean of each group is the same.
  • Use different variables as grouping variables (fat intake high 1; fat intake low 0) and compare the results.
  • Calculate anF-test for an overall comparison of means to see whether any differences are significant.
