Sagot :

The IQR of the data is 1. To find the IQR you have to arrange the numbers in numerical order and then find the median which would be 4. Then you have to find the upper and lower medians. Which you get by omitting the median in this case because there’s an odd amount of numbers. And then grouping the numbers in two sets. And then finding the median of both sets and then subtracting those numbers.
