Namespace:  System.Web.UI.DataVisualization.Charting
Assembly:  System.Web.DataVisualization (in System.Web.DataVisualization.dll)

public:
ZTestResult^ ZTest(
	double hypothesizedMeanDifference, 
	double varianceFirstGroup, 
	double varianceSecondGroup, 
	double probability, 
	String^ firstInputSeriesName, 
	String^ secondInputSeriesName
)

Parameters

Type: System::Double
Variance within the first group of data.
varianceSecondGroup
Type: System::Double
Variance within the second group of data.
probability
Type: System::Double
Alpha value. The acceptable range is between 0 and 1.
firstInputSeriesName
Type: System::String
Name of the Series object that stores the first group's data.
secondInputSeriesName
Type: System::String
Name of the Series object that stores the second group's data.
