Custom methods that are passed in will have to handle them themselves.

I did actually initially implement it like that, however then I realised that if you take all those values out you potentially screw up the calculation and given the end user no ability to override.

For example if you data is [9,4,null, null] a method that returns the mean would return 6.5 rather than 3.25.
