Solution:

1. Order the data and find the smallest value, first quartile, median, third quartile, and largest value
 15, 16, 19, 22, 22, 23, 23, 31, 38, 42, 44, 47, 50, 51, 51, 56, 63

• smallest value: 15
• first quartile: (22+22)/2 = 22
• median: 38
• third quartile: (50+51)/2 = 50.5
• largest value: 63
2. Draw a number line and plot a point about each value from step 1 3. Draw the box and whiskers Directions: Draw a box-and-whisker plot for the following:
