How to Find the IQR. IQR stands for Interquartile Range, and it is used in statistical analysis to help draw conclusions about a data set. It is often preferred over the range in measuring the spread of a data set, because it excludes most outliers. You can learn how to find the IQR by reading the following:
An Alternative Definition for IQR. In some texts, the interquartile range is defined differently. It is defined as the difference between the largest and smallest values in the middle 50% of a set of data. To compute an interquartile range using this definition, first remove observations from the lower quartile. Then, remove observations from the upper quartile. Then, from the remaining observations, compute the difference between the largest and smallest values.
