The IQR is the difference between Q3 and Q1.
The Interquartile Range Calculator on this site can calculate that interval for you. There are several methods for determining outliers in a sample. The main and most important purpose of standard deviation is to understand how spread out a data set is. Measures the difference between the minimum and maximum value in a dataset.
