How to find the interquartile range
The IQR represents the spread of the middle 50% of the data. It is a measure of variability and is less sensitive to outliers compared to the range.
The interquartile range is solved using the formula
IQR = Upper quartile - lower quartile
From the data, we get the values as follows
IQR = 42 - 28
IQR = 14
