# Statistical Characteristics

This group of functions calculates the Statistical Characteristics of the array elements:

- mean,
- variance,
- skewness,
- kurtosis,
- median,
- root-mean-square and
- standard deviation.

| Function | Description |
| --- | --- |
| MathMean | Calculates the mean (first moment) of array elements |
| MathVariance | Calculates the variance (second moment) of array elements |
| MathSkewness | Calculates the skewness (third moment) of array elements |
| MathKurtosis | Calculates the kurtosis (fourth moment) of array elements |
| MathMoments | Calculates the first 4 moments (mean, variance, skewness, kurtosis) of array elements |
| MathMedian | Calculates the median value of array elements |
| MathStandardDeviation | Calculates the standard deviation of array elements |
| MathAverageDeviation | Calculates the average absolute deviation of array elements |
