1. Creating a Box-and-Whisker Plot O To create your own box-and-whisker plot, you must first find the following values. Lowest Value Lower Quartile Median Upper Quartile Highest Value 173, 179, 181, 198, 206, 239, 246, 251, 257, 261, 295 173 295 239 181 257

2. Creating a Box-and-Whisker Plot O To create your own box-and-whisker plot, you must first find the following values. Lowest Value Lower Quartile Median Upper Quartile Highest Value 173 295 239 181 257

3. Creating a Box-and-Whisker Plot O Let’s try another example… Lowest Value Lower Quartile Median Upper Quartile Highest Value 15, 20, 25, 30, 40, 55, 60, 70 15 70 (30 + 40) ÷ 2 = 35 (20 + 25) ÷ 2 = 22.5 (55 + 60) ÷ 2 = 57.5

4. Creating a Box-and-Whisker Plot O Let’s try another example… Lowest Value Lower Quartile Median Upper Quartile Highest Value 15 70 (30 + 40) ÷ 2 = 35 (20 + 25) ÷ 2 = 22.5 (55 + 60) ÷ 2 = 57.5 70

5. Try the next example on your own. Lowest Value Lower Quartile Median Upper Quartile Highest Value 0, 1, 2, 3, 6, 6, 7, 7 0 7 (3 + 6) ÷ 2 = 4.5 (1 + 2) ÷ 2 = 1.5 (6 + 7) ÷ 2 = 6.5 07
