(reference)[http://en.wikipedia.org/wiki/Arithmetic_mean] median The median is the number separating the higher half of a data sample, a population, or a probability distribution, from the lower half (reference)[http://en.wikipedia.org/wiki/Median) mode population_standard_deviation Population standard deviation is a measure that is used to quantify the amount of variation or dispersion of a set of data values. (reference)[http://en.wikipedia.org/wiki/Standard_deviation] population_variance (Population variance)[http://en.wikipedia.org/wiki/Variance#Population_variance] standard_deviation Standard deviation is a measure that is used to quantify the amount of variation or dispersion of a set of data values. (reference)[http://en.wikipedia.org/wiki/Standard_deviation] standard_scores Standard score is a given datum's (signed) number of standard deviations above the mean. (reference)[http://en.wikipedia.org/wiki/Standard_score] Method returns a vector of scores for a vector of inputs. scores[n] is the score of v[n] variance (Sample variance)[http://en.wikipedia.org/wiki/Variance#Sample_variance]
