To obtain measures of central tendency and variability in Minitab Express:

  1. Open the data set in Minitab Express
  2. On a PC: from the menu select STATISTICS > Describe 
    On a Mac: from the menu select Statistics > Summary Statistics > Descriptive Statistics
  3. Double click the variable Online Courses Completed in the box on the left to insert it into the Variable box on the right
  4. Click on the Statistics tab and select the descriptive statistics you want displayed (e.g., Mode)
  5. Click OK

This should result in the following output:
