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

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.
