Interquartile range again

Problem:





Solution

To find the interquartile range, you first sort the data

2 3 3 3 5 6

Next, you find the 25 percentile value, which is 3 in this case.

 Next, you find the 75 percentile value, which is 5 in this case.

Finally, you subtract them and get 2, that is the interquartile range.
