Which of the following best describes the process of finding the interquartile range for a set of data?

• Add the biggest and smallest numbers.

• Place the numbers in order from least to greatest and find the middle.

• Find the difference between the maximum and the minimum.

• Subtract Q1 from Q3.

First step to finding the IQR

• Place the numbers in order and find the median

• Look for the middle number of the first half of the data Q1, and the number of second half Q3

• Subtract your Q3 - Q1

• Subtract the biggest and smallest number

How do you find the Interquartile Range or IQR?

• Q3 - Q1

• Median

• Q1 - Q3

• Maximum - Minimum

Find the IQR of the following numbers:

84, 88, 72, 74, 98, 16, 94

• 78

• 22

• 16

• There is no IQR.

Based on the box plot above, how do I find the IQR?

• 45 - 33

• 45 + 33

• 23 + 58

• 58 - 23

Find the interquartile range (IQR) of the data set:

22, 12, 8, 8, 13, 11, 21, 19, 15, 21
