Computes the population standard deviation of a sequence of values that are obtained by invoking a transform function on each element of the input sequence.

Namespace: MongoDB.Driver.Linq
Assembly: MongoDB.Driver (in MongoDB.Driver.dll) Version: 2.10.0+569905ff5e778c38ea19d9d0392496a83e1704ed

Syntax

Copy

public static double StandardDeviationPopulation<TSource>(
	this IEnumerable<TSource> source,
	Func<TSource, double> selector
)

<ExtensionAttribute>
Public Shared Function StandardDeviationPopulation(Of TSource) ( 
	source As IEnumerable(Of TSource),
	selector As Func(Of TSource, Double)
) As Double

[<ExtensionAttribute>]
static member StandardDeviationPopulation : 
        source : IEnumerable<'TSource> * 
        selector : Func<'TSource, float> -> float

Parameters

source: Type: System.Collections.GenericIEnumerableTSource
A sequence of values to calculate the population standard deviation of.
selector: Type: SystemFuncTSource, Double
A transform function to apply to each element.

Type Parameters

TSource: The type of the elements of source.

Return Value

Type: Double
The population standard deviation of the sequence of values.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerableTSource. When you use instance method syntax to call this method, omit the first parameter.
