Why is the mean vulnerable to outliers while the median and mode are not?
What will be an ideal response?
The mean is calculated by summing all values and dividing by the total number of observations. Thus, the larger or smaller an outlier, the more the mean will increase or decrease. The median and mode, however, are not vulnerable to outliers because by the definition an outlier is found at the extreme end of a distribution, not in the middle, and is not the most frequently observed value.
