Enum Constant Details

AVERAGE
The [mean](https://en.wikipedia.org/wiki/Arithmetic_mean) of N measurements over the stated period. 
MAXIMUM
The [maximum](https://en.wikipedia.org/wiki/Maximal_element) value of N measurements over the stated period. 
MINIMUM
The [minimum](https://en.wikipedia.org/wiki/Minimal_element) value of N measurements over the stated period. 
COUNT
The [number] of valid measurements over the stated period that contributed to the other statistical outputs. 
TOTALCOUNT
The total [number] of valid measurements over the stated period, including observations that were ignored because they did not contain valid result values. 
MEDIAN
The [median](https://en.wikipedia.org/wiki/Median) of N measurements over the stated period. 
STDDEV
The [standard deviation](https://en.wikipedia.org/wiki/Standard_deviation) of N measurements over the stated period. 
SUM
The [sum](https://en.wikipedia.org/wiki/Summation) of N measurements over the stated period. 
VARIANCE
The [variance](https://en.wikipedia.org/wiki/Variance) of N measurements over the stated period. 
_20PERCENT
The 20th [Percentile](https://en.wikipedia.org/wiki/Percentile) of N measurements over the stated period. 
_80PERCENT
The 80th [Percentile](https://en.wikipedia.org/wiki/Percentile) of N measurements over the stated period. 
_4LOWER
The lower [Quartile](https://en.wikipedia.org/wiki/Quartile) Boundary of N measurements over the stated period. 
_4UPPER
The upper [Quartile](https://en.wikipedia.org/wiki/Quartile) Boundary of N measurements over the stated period. 
_4DEV
The difference between the upper and lower [Quartiles](https://en.wikipedia.org/wiki/Quartile) is called the Interquartile range. (IQR = Q3Q1) Quartile deviation or Semiinterquartile range is onehalf the difference between the first and the third quartiles. 
_51
The lowest of four values that divide the N measurements into a frequency distribution of five classes with each containing one fifth of the total population. 
_52
The second of four values that divide the N measurements into a frequency distribution of five classes with each containing one fifth of the total population. 
_53
The third of four values that divide the N measurements into a frequency distribution of five classes with each containing one fifth of the total population. 
_54
The fourth of four values that divide the N measurements into a frequency distribution of five classes with each containing one fifth of the total population. 
SKEW
Skewness is a measure of the asymmetry of the probability distribution of a realvalued random variable about its mean. The skewness value can be positive or negative, or even undefined. Source: [Wikipedia](https://en.wikipedia.org/wiki/Skewness). 
KURTOSIS
Kurtosis is a measure of the "tailedness" of the probability distribution of a realvalued random variable. Source: [Wikipedia](https://en.wikipedia.org/wiki/Kurtosis). 
REGRESSION
Linear regression is an approach for modeling twodimensional sample points with one independent variable and one dependent variable (conventionally, the x and y coordinates in a Cartesian coordinate system) and finds a linear function (a nonvertical straight line) that, as accurately as possible, predicts the dependent variable values as a function of the independent variables. Source: [Wikipedia](https://en.wikipedia.org/wiki/Simple_linear_regression) This Statistic code will return both a gradient and an intercept value.
