<span>In statistics, an outlier is an observation point that is distant from other observations.
Given the points
15, 23, 24, 26, 27 and 35
Notice, that the points 15 and 35 are distance from the other points and hence are outliers.
The mean of the observations including the outliers is given by

The mean of the observations without the outliers is given by

Therefore, </span>when <span>the outliers are removed,
the mean remains the same.</span>
