A disadvantage of the mean as measure of central tendency is that?
-
is affected by extreme values
- can only be used for continuous data
- cannot be used to measure the qualities of a population
- cannot be determined in group data
The correct answer is: A
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.
