In the pop-up window, select “Find the Interquartile”. You can also use the search.

The interquartile range (IQR) is the difference between the third and first quartile. Interquartile is a characteristic of the distribution of the value and is a robust analogue of variance. Together, the median and interquartile range can be used instead of mathematical expectation and variance in the case of large-emission distributions, or if the latter cannot be calculated.
