Parameters

Values. Array of numeric arguments corresponding to population.

Description

The DispersionP method calculates variance for population.

Comments

At the calculation it is assumed that arguments represent the entire population.

Example

Sub Main;

Var

st: Statistics;

d0: Double;

y: Array Of Double;

Begin

y := New Double[10];

y[00] := 1.6;

y[01] := 1.7;

y[02] := 1.8;

y[03] := 1.9;

y[04] := 2;

y[05] := 2.1;

y[06] := 2.2;

y[07] := 2.3;

y[08] := 2.4;

y[09] := 2.8;

st := New Statistics.Create;

d0 := st.DispersionP(y);

Debug.WriteLine("Variance: " + d0.ToString);

End Sub Main;
