  1. 12.3 Box-and-Whisker Plots Objectives: Find the range, quartiles, and inter-quartile range for a data set. Make a box and-whisker plot for a data set. Standards: 2.6.8E Analyze and display data in box- and-whisker plots.

  2. These five values are referred to collectively as the “five point summary” for the data set.

  3. Find the 5 point summary and the IQR for the data set below. Identify any outliers. TRY THIS: min = 2 Q1 = 10 median = 33.5 Q3 = 51 max = 83 IQR = 41 Low Outliers? Q1 – 1.5(IQR) = 10 – 1.5(41) = 10 – 61.5 = -51.5 No values below -51.5 No low outliers High Outliers? Q3 + 1.5(IQR) = 51 + 1.5(41) = 51 + 61.5 = 112.5 No values above 112.5 No high outliers
