  2. 2. Box-and-Whisker Plots • A box-and-whisker-plot is a data display that divides data values into four parts. Ordered data are divided into a lower and upper half by the median.
  3. 3. Making a Box-and-Whisker Plot Roller Coaster Heights (m) 35 42 44 60 60 70 76 78 81 100 Median = Lower half Upper half 35 42 44 60 60 70 76 78 81 100 Lower Quartile Upper Quartile 30 40 50 60 70 80 90 100 110 35 44 65 78 100 Lower Extreme Upper Extreme 60 42 100 81 78 70 60 76 44 35 Put in order from least to greatest. (60 + 70) ÷ 2 = 65
