Minitab Instructions: Checking Conditions

If you feel that you need to look at the two samples using histograms, launch Minitab with the data in the worksheet by right-clicking here and choosing "Save Target As" to download the file to your computer. Then find the downloaded file and double-click it to open it in Minitab. Note: a dialog box will likely appear that says "A copy of the content of this file will be added to the current project"—just click "OK."

Reminder: To construct histograms of the data:

  1. Choose: Graph -> Histogram. Choose "Simple" and click "OK."
  2. Under "Graph Variables" enter the columns where the data from the two samples are.
  3. Click "OK."
