Descriptive statistics for a supplied numeric array in one call
Descriptive statistics for a supplied numeric array in one call: count, sum, mean, median, mode, variance and standard deviation in both sample and population form, min, max, range, the quartiles and interquartile range, skewness, kurtosis, and any requested percentiles. Percentiles use a named interpolation method so the result is reproducible rather than implementation-defined.
