Some statistics can be badly affected by outliers in the data, while others are
robust. It is often worth considering how the results are affected by such observations.
The dataset worksheet is displayed.
The value is enclosed in square brackets  indicating it will be
excluded from further analysis.
The results are recalculated without the
and the analysis report updated.
After excluding the outliers the mean estimate has changed from 26.2 to 27.8 and the
confidence interval is narrower.
