The middle value (or average of the two middle values) in a data set is referred to as the 50th percentile. It divides the data set exactly in half.
The 25th percentile is the middle value (or average of the two middle values) in the lower half of the data set.
The 75th percentile is the middle value (or average of the two middle values) in the upper half of the data set.
The IQR = 75th Percentile - 25th Percentile
