1 12.4 Box-and-Whisker Plots

2 Definitions: Minimum: Smallest number in the set of data (ordered least to greatest) Maximum: Largest number in the set of data (ordered least to greatest) Median: Middle number in the set of data (ordered least to greatest) 1st Quartile: The middle number of the lower half of the data (ordered least to greatest) 3rd Quartile: The middle number of the upper half of the data (ordered least to greatest)

3 When making a Box-and-Whisker Plot:
Put numbers in order from least to greatest Find the minimum, maximum, and median Find the 1st quartile and the 3rd quartile Represent the data in box-and- whisker format

4 Example 1 Make a box-and-whisker plot to represent the set of data:

5 Example 1 Work

6 Example 2 Make a box-and-whisker plot to represent the set of data:

7 Example 2 Work
