MathExtensions.Median not following general definition of median #22
Description
The MathExtensions.Median() function doesn't adhere to the statistical definition of median, that can be found on Wikipedia. This definition states that the value choosen depends on the value count:
If there is an odd number of numbers, the middle one is picked.
If there are an even number of observations, then there is no single middle value; the median is then usually defined to be the mean of the two middle values.
Current implementation takes the value at count / 2, that differs when value count is even with the above definition. When the value count is odd, the current implementation ok.
