Minitab® – Central Tendency
Central Tendency and Variability Section
This example will use data collected from a sample of students enrolled in online sections of STAT 200 during the Summer 2020 semester. These data can be downloaded as a CSV file:

- Open the data set in Minitab
- From the tool bar, select Stat > Basic Statistics > Display Descriptive Statistics...
- Double click the variable Online Courses Completed in the box on the left to insert it into the Variables box on the right
- Click on the Statistics button and select the descriptive statistics you want displayed (e.g., Variance, Interquartile range, Mode)
- Click OK
- Click OK
This should result in the following output:
|Variable||N||N*||Mean||SE Mean||StDev||Variance||Minimum||Q1||Median||Q3||Maximum||IQR||Mode||N for Mode|
|Online Courses Completed||324||19||5.6975||0.4579||8.2429||67.945||0.0000||1.0000||3.0000||6.0000||70.0000||5.000||0||57|
