Concept:The mean is a measure of central tendency that gets easily distorted by unusually high or low values.
Explanation:The mean is calculated as
number of valuessum of all values.
Because every value is included in its calculation, one extremely large or extremely small value can shift the mean significantly.
Such extreme values are called outliers.
When outliers are present, the mean no longer represents the typical value of the data set.
This makes the mean unsuitable for skewed distributions.
Being influenced by extreme values is therefore a major disadvantage of the mean.
