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

7.SP.B.3

Judge how much two data sets with similar spread overlap, measuring the gap between their centers in units of that spread.

The recent mean is higher, but compare individual weeks too.

How many earlier weeks had more orders than the recent mean of 28?   weeks

2.
For the earlier period, find each weekly count's absolute distance from the mean of 24. Average all six distances.

What is the earlier period's MAD?   orders
