Computes the sample 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: 2.8.0+cc573f3e1f48f39162b4b680e921a623e127e8fa

Syntax

Copy

public static decimal StandardDeviationSample<TSource>(
	this IMongoQueryable<TSource> source,
	Expression<Func<TSource, decimal>> selector
)

<ExtensionAttribute>
Public Shared Function StandardDeviationSample(Of TSource) ( 
	source As IMongoQueryable(Of TSource),
	selector As Expression(Of Func(Of TSource, Decimal))
) As Decimal

[<ExtensionAttribute>]
static member StandardDeviationSample : 
        source : IMongoQueryable<'TSource> * 
        selector : Expression<Func<'TSource, decimal>> -> decimal

Parameters

source: Type: MongoDB.Driver.LinqIMongoQueryableTSource
A sequence of values to calculate the population standard deviation of.
selector: Type: System.Linq.ExpressionsExpressionFuncTSource, Decimal
A transform function to apply to each element.

Type Parameters

TSource: The type of the elements of source.

Return Value

Type: Decimal
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 IMongoQueryableTSource. When you use instance method syntax to call this method, omit the first parameter.
