alleryCalling the mean not robust means that it is
Ahard to compute for big data
Balways equal to the median
Cunaffected by outliers
Deasily pulled by extreme values
Answer & Solution
Correct answer: D. easily pulled by extreme values
1. A robust statistic stays steady when odd values appear.
2. The mean uses every value, so an outlier changes it.
3. So not robust means easily distorted by extreme values.
The mean equals the median only in symmetric data, and it is not hard to compute.
