Class ZTestResult

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

Constructors

ZTestResult()

Initializes a new instance of the ZTestResult class.

Declaration
public ZTestResult()

Properties

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

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

The first series variance.

ProbabilityZOneTail

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

Declaration
public double ProbabilityZOneTail { get; }
Property Value
Type Description

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

The Z critical value two tail.

ZValue

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

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

The Z value.
