the reason for introducing the median was that – especially in the event of a small sample size – it is far less sensitive to the inclusion of an outlier (extraordinary gain/loss, e.g. 2 standard deviations away from the mean), and it regularly corresponds to a real value (one out of the sample size).

A median is described as the number separating the higher half of a sample from the lower half (http://en.wikipedia.org/wiki/Median).

From today onward I’ll take out the ‘Averages’.

Also, just wanted to say I really like the addition of the median to the stats. In fact, maybe the average is no longer needed? (I’m not sure if it adds significant value now)
