Mar 25­3:38 PM
Mar 25­3:40 PM
Box­and­Whisker Plot Practice WS
1. 14
2. 15
11. The game scores ranged from 24­50 so the range is 26.
3. 4
12. The middle 50% of the data shows a range from 28­38.
4. 25%
13. The upper quartile has more variability. Games scores over 28 had a large spread of data.
5. 25%
6. There is more variability in the upper half because the whisker is longer.
7. 25 is an extreme because 75% of the volunteer ages are between 10­18 and the graph is closer together in this range.
14. Minimum, maximum, Q1, Q3, and median are the 5­number summary. The 5 points are graphed above a number line to show the variability (spread) of the data.
8. There is a greater variability (spread of data) for volunteers over 18.
15.
9.
The ages of the first 15 presidents ranged from 48 to 68. Each quartile of data had a similar spread (variability).
10. There is not a large spread or variability in the data. Mar 25­3:43 PM
