One of the simplest methods for detecting outliers is the use of box plots. This way is generally more powerful than the mean and standard deviation way of detecting outliers, but nevertheless, it can be too aggressive in classifying values that aren’t really extremely different. We may use the median with the interquartile variety, or we may use the mean with the typical deviation.
While both, along with other statistical values, ought to be calculated when describing data, if only one can be used, the median can supply a better estimate of a normal value in a particular data set whenever there are really huge variations between values. It’s possible to think of them as a fence that cordons off the outliers from each one of the values which are inside most of the data. If you own a selection of values that something falls under, rarely do you receive an equal distribution of all of the values.
