Properties

	Name	Description
	Max	Gets the maximum of the data values.
	Mean	Gets the arithmetic mean (average) of the data values.
	Min	Gets the minimum of the data values.
	N	Gets the number of data values that were added.
	PopulationStandardDeviation	Gets the population standard deviation: square root of the error sum of squares divided by N.
	PopulationVariance	Gets the population variance: error sum of squares divided by N.
	SampleStandardDeviation	Gets the sample standard deviation: square root of the error sum of squares divided by (N-1).
