MinitabExpress – Central Tendency
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 Minitab Express Project or as a CSV file:
To obtain measures of central tendency and variability in Minitab Express:
- Open the data set in Minitab Express
- On a PC: from the menu select STATISTICS > Describe
On a Mac: from the menu select Statistics > Summary Statistics > Descriptive Statistics
- Double click the variable Online Courses Completed in the box on the left to insert it into the Variable box on the right
- Click on the Statistics tab and select the descriptive statistics you want displayed (e.g., Mode)
- Click OK
This should result in the following output:
|Variable||N||N*||Mean||SE Mean||StDev||Minimum||Q1||Median||Q3||Maximum||Mode||N for Mode|
|Online Courses Completed||324||19||5.6975||0.4579||8.2429||0.0000||1.0000||3.0000||6.0000||70.0000||0||57|
