[~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.
