Class 1 has more variability because both the range and interquartile range are greater than class 2, meaning the data is more spread out.

Importance of range and interquartile range

Range gives the spread of the whole data set, while the interquartile range gives the spread of the middle half of a data set.

  • A high range means a high variability of the data set.
  • A low interquartile range means clustered middle data.

Thus, we can conclude that, Class 1 has more variability because both the range and interquartile range are greater than class 2, meaning the data is more spread out.
