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

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
