Question

What is the interquartile range of the data set?

{40, 48, 62, 60, 62, 40, 25, 50, 20, 30, 55}



Enter the answer in the box.

Answer 1

The answer is 30.

How to get 30 as the answer:

First, you order the numbers from least to greatest (20, 25, 30, 40, 40, 48, 50, 55, 60, 62, 62) . Now, find the middle number of the data set. (48) Next, you find the middle of each side. (left side=30. right side=60) Next once you've done that, you subtract 30 from 60 which leaves you with 30 as the answer.

p.s. I took the k12 unit 6 test review and got a B so I CAN confirm, this is correct

Answer 2
