This refers to Barry Bonds' home run-totals for the years 1991-2005:

25, 34, 46, 37, 33, 42, 40, 37, 34, 49, 73, 46, 45, 45, 5

The first quartile of this distribution, 34, is also called the 25th percentile, indicating that approximately 25% of the observations fall below this value. The third quartile of this distribution, 46, is also called the 75th percentile, indicating that approximately 75% of the observations fall above this value. In this distribution, what percent of the observations actually fall outside of the IQR? That is, what percent of the observations fall below 34

quietus · Answer

IQR = 75th percentile - 25th percentile, = 46-34=12 
5,25,33,34,34,37,37,40,42,45,45,46,46,49,73
