A. is affected by extreme values
B. can only be used for continuous data
C. cannot be used to measure the qualities of a population
D. cannot be determined in group data
Correct Answer: Option A
A. is affected by extreme values
Explanation
The important disadvantage of mean is that it is sensitive to extreme values/outliers, especially when the sample size is small. Therefore, it is not an appropriate measure of central tendency for skewed distribution. Mean cannot be calculated for nominal or nonnominal ordinal data.
