Which measure of variability——range or IQR——best describes the spread of the dataset?
1 answer
If the dataset contains outliers, the interquartile range (IQR) may be a better measure of variability as it is not affected by extreme values. The range, on the other hand, is sensitive to outliers and may not accurately represent the spread of the dataset in such cases. However, if there are no outliers and the data is relatively evenly distributed, the range may be an appropriate measure of variability. Ultimately, the choice between range and IQR will depend on the specific characteristics of the dataset.
