Variability of a data distribution that is represented by a box plot can be determined by the interquartile range (IQR) = Upper Quartile (Q3) - Lower Quartile (Q1).

See the diagram attached below to understand how to get the Q3 and Q1 of the data distribution.

In conclusion, variability is a measure of IQR. The greater the IQR of a box plot, the greater the variety. Thus, the store that has a greater variety of numbers of wristbands sold is the store whose box plot has a greater IQR value.
