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:
Descriptive Statistics: Online Courses Completed
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 |
