The interquartile range (IQR) is a measure of statistical dispersion, or in simpler terms, it's a measure of where the "middle half" is in a data set. Here's how you calculate it:

1. Arrange the data in increasing order.

2. Calculate the first quartile (Q1), which is the middle number between the smallest number and the median of the data set.

3. Calculate the third quartile (Q3), which is the middle value between the median and the highest value of the data set.

4. Subtract Q1 from Q3. This value is the interquartile range.

The IQR can be used to identify outliers in the data. Any number less than Q1 - 1.5*IQR or greater than Q3 + 1.5*IQR is considered an outlier.
