**Public Function StandardDeviationArray( _
ByRef vValues As Variant _
) As Variant**

**Standard deviation of numeric values. **

More efficient version of the StandardDeviation Function but with restrictions on the arguments it accepts.

**Examples:** StandardDeviationArray(Array(12, 34, 56)) = 22
StandardDeviationArray(SampleData) = 23.7393977642901

**See also:** StandardDeviation Function
StandardDeviationPopulationArray Function
VarianceArray Function

STDEVA Function (Microsoft Excel)

**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 standard deviation of the numeric values. Function returns Null if there are fewer than two numeric values in the array, 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:** StandardDeviationArray and StandardDeviationPopulationArray replace the StandardDeviationVariantVector 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. Copyright 1996-1999 Entisoft
