Q:
# What is the interquartile range of the data set? Enter the answer in the box. Key: 1|5 means 15 A stem-and-leaf plot with a stem value of 1 with a leaf value of 0, a stem value of 2 with a leaf value of 3, 3, 8, a stem value of 3 with a leaf value of 3, a stem value of 4 with a leaf value of 5, a stem value of 5, a stem value of 6, a stem value of 7, a stem value of 8 with a leaf value of 0, and a stem value of 9 with a leaf value of 0.

Accepted Solution

A:

To find the interquartile range, you would list the data that comes from the stem and leaf plot:

10, 23, 23, 28, 33, | 45, 56, 67, 80, 90; | marks where the median would be.

The 2 numbers underlined represent he 1st(lower) and 3rd(upper) quartiles. Subtract these to find the interquartile range.

67 - 23 = 44

44 is the IQR.

10, 23, 23, 28, 33, | 45, 56, 67, 80, 90; | marks where the median would be.

The 2 numbers underlined represent he 1st(lower) and 3rd(upper) quartiles. Subtract these to find the interquartile range.

67 - 23 = 44

44 is the IQR.
