The Z-test formula performs a Z-test using normal distribution.

public:
 System::Web::UI::DataVisualization::Charting::ZTestResult ^ ZTest(double hypothesizedMeanDifference, double varianceFirstGroup, double varianceSecondGroup, double probability, System::String ^ firstInputSeriesName, System::String ^ secondInputSeriesName);

public System.Web.UI.DataVisualization.Charting.ZTestResult ZTest (double hypothesizedMeanDifference, double varianceFirstGroup, double varianceSecondGroup, double probability, string firstInputSeriesName, string secondInputSeriesName);

member this.ZTest : double * double * double * double * string * string -> System.Web.UI.DataVisualization.Charting.ZTestResult

Public Function ZTest (hypothesizedMeanDifference As Double, varianceFirstGroup As Double, varianceSecondGroup As Double, probability As Double, firstInputSeriesName As String, secondInputSeriesName As String) As ZTestResult

Parameters

hypothesizedMeanDifference: Double

Hypothesized difference between the means of the data groups.

varianceFirstGroup: Double

Variance within the first group of data.

varianceSecondGroup: Double

Variance within the second group of data.

probability: Double

Alpha value. The acceptable range is between 0 and 1.

firstInputSeriesName: String

Name of the Series object that stores the first group's data.

secondInputSeriesName: String

Name of the Series object that stores the second group's data.

Returns

ZTestResult

A ZTestResult object.

Examples

The following code demonstrates how to use this formula.

Dim result As ZTestResult = Chart1.DataManipulator.Statistics.ZTest(0.2, 2.5, 4.5, 0.05, "Series1", "Series2")

ZTestResult result = Chart1.DataManipulator.Statistics.ZTest(0.2, 2.5, 4.5, 0.05, "Series1", "Series2");
