Module 4 Checkpoint: Centre, Spread, and Distribution Shape
Scenario
A team reports an average handling time of 6.2 minutes. The times are 2, 2, 3, 3, 3, 4, 4, 5, 6, and 30 minutes.
Questions
- Calculate the median and say why it differs from the mean.
- Which of the two better describes a typical call here?
- What does the 30-minute call most likely represent, and should it be removed?
- What does the range tell you that neither the mean nor the median does?
- Write the one-sentence summary you would put in a report.
Pass Standard
You pass when you report both the mean and the median where they disagree, and can explain what the gap between them means.
