Practice question · Select all that apply
In the dataset 2, 4, 4, 5, 10 the largest value is changed from 10 to 100. Select every statistic that changes as a result.
Hints
- Recompute the ordering: does the value's position in the sorted list change?
- Only statistics that use the magnitude of the largest value can react.
Show the answer
- A. Standard deviation
- B. Mean
- C. Range
Why
The mean rises from 5 to 23, the range from 8 to 98, and the spread balloons. The median stays 4 (the third of five sorted values, and 100 is still last) and the mode stays 4. This single edit is a compact demonstration of robustness.
