Lesson 10.4 Box and Whisker Plots Notes – – A represents a data set along a number line by using the least value, the greatest value, and the box and whisker plot quartiles of the data. A box and whisker plot shows the variability of a data set. The five numbers that make up the box and whisker plot are called the five number summary of the data set. __________________________________________________________________________________________________ Ex. # 1 Making a Box and Whisker Plot – Make a box and whisker plot for the numbers of text messages received: 15, 20, 14, 38, 30, 36, 30, 30, 27, 26, 33, 35 __________________________________________________________________________________________________ Ex. # 2 Analyzing a Box and Whisker Plot – The box and whisker plot the times that the students in a gym class spent on an obstacle course. a. What fraction of the spent 110 seconds or less on the obstacle course? b. Are the data more spread out below the first quartile or above the third quartile? Explain.
