Interquartile Range
IQR in R
In the last exercise, we calculated the IQR by finding the quartiles using R and finding the difference ourselves. The stats library has a function that can calculate the IQR all in one step.
The IQR() function takes a dataset as a parameter and returns the Interquartile Range.
Instructions

Let’s calculate the IQR again, but this time, use the stats function.
Create a variable named interquartile_range and set it equal to the result of calling IQR() using songs as an argument.
