WebAug 24, 2024 · How to calculate IQR in an odd dataset. Now, the next step is to calculate the IQR which stands for Interquartile Range. This is the difference/distance between the lower quartile (Q1) and the upper quartile (Q3) you calculated above. As a reminder, the formula to do so is the following: IQR = Q3 - Q1 To find the IQR of the dataset from above:
The interquartile range is found by subtracting the Q1 value from the Q3 value: Q1 is the value below which 25 percent of the distribution lies, while Q3 is the value below which 75 percent of the distribution lies. You can think of Q1 as the median of the first half and Q3 as the median of the second half of the distribution.
