How is the range of a data set found?
AMaximum minus minimum
BMaximum plus minimum
CMedian minus the mean
DMean minus the mode
Answer & Solution
Correct answer: A. Maximum minus minimum
1. The range is the most straightforward measure of dispersion.
2. It is the difference between the maximum and the minimum values in the set.
3. The range therefore tells you how far apart the largest and smallest values are.
4. Because it uses only the two extreme values, the range is very sensitive to outliers.
