As a general rule,an interquartile range is a better estimate of variability than the IQR.

Question

Quizplus · Accepted Answer

This statement is incorrect. The interquartile range (IQR) is a measure of variability that is the difference between the third quartile (Q3) and the first quartile (Q1) of a dataset. The IQR is a useful measure of variability because it is not affected by extreme values or outliers in the dataset. On the other hand, "the IQR" (which is not a commonly used term) is not a meaningful concept, as it is unclear what exactly is being referred to. Therefore, the statement presented in the question is false.
