StatisticFormula.TTestEqualVariances(Double, Double, String, String) Method

Definition

Namespace:

System.Web.UI.DataVisualization.Charting

Assembly:

System.Web.DataVisualization.dll

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");
