Family Gatherings by the Numbers
Ledet Family Ages: 1, 44, 3, 42, 46, 74, 75, 21, 74, 70, 40, 41, 45 Average: 44.3 years old
1 Order the Ages from Least to Greatest:
Then compute: Minimum Q1 Median Q3 Maximum Range Interquartile Range (IQR)
Watson Family Ages: 70, 68, 69, 72, 65, 75, 65, 78, 70, 72, 71, 70 Average: 70.4 years old
2 Order the Ages from Least to Greatest:
Then compute: Minimum Q1 Median Q3 Maximum Range Interquartile Range (IQR)
Box Plots - Visualizing Shape
Make box plots to each family’s age distribution on the number lines below. Hint: Plot the 5-Number Summaries, draw a box around the IQR (from Q1 to Q3), let the median split the box into 2 parts, and add whiskers from the box to the minimum and maximum values.

Compare and Contrast
5 For which family gathering was the average age more typical? How do you know?
6 What else do you Notice and Wonder about the data from these two family gatherings?
7 We plotted both of these box plots on number lines with the same scale. What are the pros and cons of that choice?
