Question

In the data set below, what is the interquartile range?
34 60 65 70 72

Answer 1

The Interquartile Range or (IQR) is 24

Explanation:

Since the data set is ordered, we don't need to order it.

Now, to find the interquartile range:

First, find median which is 65 since it is in the middle

Next, we find the median in Quartile 1 and Quartile 3 (Quartile 2 is median)

So in Quartile 1, median is 47

Quartile 2, median is 71

Now find the range of those two:

71 - 47 = 24

Hope this helps!!
