Quizplus · Accepted Answer

The interquartile range (IQR) is a measure of the spread or variability of a set of data. It is calculated as the difference between the upper and lower quartiles (the 75th and 25th percentiles) of the data. The IQR gives a sense of the spread of the middle 50% of the data, and is often used as an alternative to the standard deviation when the data is skewed or contains outliers. Therefore, the statement is true.
