----------------------------------------------------------------
[~srowen], I agree these are not exactly difficult to implement, but I guess
these should be there in the library for the sake of completeness. For
instance, while doing EDA on the data, one would use the
{{Statistics.colStats(observations)}} and would expect to get all the required
summary data similar to what {{R}}'s {{summary(dataset)}} does. For the same
reasons, while we are at it, we should also add 25th and 75th percentiles as
well.
