About this worksheet
What students practice
- Students measure differences between centers in units of a shared MAD or IQR.
- Students use data and box plots to judge overlap between distributions with similar spread.
- Students distinguish a difference in typical orders from differences in individual weekly orders.
How to use
Use after teaching MAD and IQR. Have students show their calculations on scratch paper, then discuss what center gaps do and do not reveal about weekly orders.
Curriculum
Common Core standard covered
Judge how much two data sets with similar spread overlap, measuring the gap between their centers in units of that spread.
