The t-test with equal variances formula performs a t-test using Student's t-distribution with equal variances.

public:
 System::Web::UI::DataVisualization::Charting::TTestResult ^ TTestEqualVariances(double hypothesizedMeanDifference, double probability, System::String ^ firstInputSeriesName, System::String ^ secondInputSeriesName);

public System.Web.UI.DataVisualization.Charting.TTestResult TTestEqualVariances (double hypothesizedMeanDifference, double probability, string firstInputSeriesName, string secondInputSeriesName);

member this.TTestEqualVariances : double * double * string * string -> System.Web.UI.DataVisualization.Charting.TTestResult

Public Function TTestEqualVariances (hypothesizedMeanDifference As Double, probability As Double, firstInputSeriesName As String, secondInputSeriesName As String) As TTestResult

Parameters

hypothesizedMeanDifference: Double

Hypothesized difference between the means of the data groups.

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

TTestResult

A TTestResult object.

Examples

The following code demonstrates how to use this formula.

Dim result As TTestResult = Chart1.DataManipulator.Statistics.TTestPaired(0.2, 0.05, "Series1", "Series2")

TTestResult result = Chart1.DataManipulator.Statistics.TTestPaired(0.2, 0.05, "Series1", "Series2");
