Class TTestResult

The result of statistical T test is stored in this class. If the T value is closer to 0.0 than TCriticalValueTwoTail or even TCriticalValueOneTail, then we can't deduce that D(hypothesized difference) is not good mean value difference. In other case ( TCriticalValueTwoTail is closer to 0.0 than TValue), there is a huge probability that hypothesized difference D hadn't been chosen correctly.

Constructors

TTestResult()

Initializes a new instance of the TTestResult class.

Declaration
public TTestResult()

Properties

DegreeOfFreedom

Gets number of degrees of freedom of T variable student's distribution.

Declaration
public double DegreeOfFreedom { get; }
Property Value
Type Description
System.Double

The degree of freedom.

FirstSeriesMean

Gets first series mean value. Series represents sample from studied population.

Declaration
public double FirstSeriesMean { get; }
Property Value
Type Description
System.Double

The first series mean.

FirstSeriesVariance

Gets first series variance. Series represents sample from studied population.

Declaration
public double FirstSeriesVariance { get; }
Property Value
Type Description
System.Double

The first series variance.

ProbabilityTOneTail

Gets the probability that the random variable has values at the tail, assuming that null hypothesis is true.

Declaration
public double ProbabilityTOneTail { get; }
Property Value
Type Description
System.Double

The probability T one tail.

ProbabilityTTwoTail

Gets the probability that the random variable has values at the tails, assuming that null hypothesis is true.

Declaration
public double ProbabilityTTwoTail { get; }
Property Value
Type Description
System.Double

The probability T two tail.

SecondSeriesMean

Gets second series mean value. Series represents sample from studied population.

Declaration
public double SecondSeriesMean { get; }
Property Value
Type Description
System.Double

The second series mean.

SecondSeriesVariance

Gets second series variance. Series represents sample from studied population.

Declaration
public double SecondSeriesVariance { get; }
Property Value
Type Description
System.Double

The second series variance.

TCriticalValueOneTail

Gets critical value of T which corresponds to Alpha probability. The area under normal probability density curve of tail is equal to alpha probability.

Declaration
public double TCriticalValueOneTail { get; }
Property Value
Type Description
System.Double

TCriticalValueTwoTail

Gets critical value of T which corresponds to Alpha probability. The area under normal probability density curve of two symmetrical tails is equal to alpha probability.

Declaration
public double TCriticalValueTwoTail { get; }
Property Value
Type Description
System.Double

The T critical value two tail.

TValue

Gets calculated T value. ( Value of normally distributed random variable with mean=0, and variance=1 ).

Declaration
public double TValue { get; }
Property Value
Type Description
System.Double

The T value.
