Variance Population Array Function
Math Statistics Class

Public Function VariancePopulationArray( _
    ByRef vValues As Variant _
    ) As Variant

Population variance of numeric values.
More efficient version of the VariancePopulation Function but with restrictions on the arguments it accepts.

Examples: 
    VariancePopulationArray(Array(12, 34, 56)) = 322.666666666667
    VariancePopulationArray(SampleData) = 557.43336483932

vValues: Numeric-type array or Variant array containing only numeric elements. This function is NOT affected by the current setting of the StatVarType Property. It assumes that vValues is an array that contains only numeric elements.
Return value: Function returns the population variance of the numeric values. Function returns Null if the array is empty, or if there is some type of error, such as if the argument is a Variant array which contains an Object reference or String.
v1.5 Note: VarianceArray and VariancePopulationArray replace the VarianceVariantVector function, which has been removed from ArrayArithmetic Class. This function is slightly different in that it examines all of the elements in the array from its lower bound through its upper bound.
