Answer: If the data has outliers

Step-by-step explanation:

  • The range is defined as the difference between the maximum and minimum data values in a data set.  It give the estimate of the spread of the data.
  • The interquartile range in statistics is defined as the difference between the first and the third quartiles. It also gives the estimate of the spread of the data.

But if a data has outliers then it might not give a true estimation of the spread of data. Then the interquartile range would be better for describing the spread of  a data set than the range because in ineterquartile range we exclude the outliers so that the interquartile range works .
