11-85.

The owner of Universal Widgets has two teams of employees and wants to know which team is working the “best.” The assistant manager gathered data for the number of widgets made per team member on various days. He presented the data the owner as two boxplots, shown below. The owner is confused. Homework Help ✎

box plots

  1. Help the owner decide which team is working the “best” by comparing center, shape, spread, and outliers.

    Which team appears to work faster?
    Which team is more consistent?

    Team 2's median is greater, hence they work faster.
    Team 1's IQR is almost half that of Team 2, so they are more consistent.

  2. Which team had smaller standard deviation?

    Which team's data is less spread out?
