public class StandardDeviationFunction : StatFunction
Xceed Toolkit Plus for WPF v5.1 Documentation
Class that represents the Standard Deviation statistical function, which is the measure of the degree of dispersion of sample or population data from the mean value.
The Standard Deviation function is not supported when using a remote data source.

'Usage Dim instance As StandardDeviationFunction
public class StandardDeviationFunction : StatFunction
The EntirePopulation property allows the Standard Deviation statistical function to calculate its result on population data rather than sample data.
Null (Nothing in Visual Basic) and DBNull values will be ignored.

| Name | Description | |
|---|---|---|
 | StandardDeviationFunction Constructor | Overloaded. Initializes a new instance of the StandardDeviationFunction class. |
| Name | Description | |
|---|---|---|
 | EntirePopulation | Gets or sets a value indicating whether the result is calculated for an entire population. |
| ResultPropertyName | Gets or sets the unique, case-sensitive property name from which the result of the statistical function can be retrieved. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| SourcePropertyName | Gets or sets the name of the column whose values will be used to calculate the result of the statistical function. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| Name | Description | |
|---|---|---|
 | IsInitialized | Gets a value indicating whether the Initialize method has been called, indicating that the types in which the values will be accumulated have been initialized. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
 | IsSealed | Gets a value indicating whether an instance of a statistical function is in an immutable state. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| PrerequisiteFunctions | Overridden. Gets a list of the statistical functions whose results are required by the current function in order to calculate its own result. |
| RequiresAccumulation | Overridden. Gets a value indicating whether the statistical function needs to accumulate its own results. |
| Name | Description | |
|---|---|---|
 | GetSourcePropertyNames | (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| Name | Description | |
|---|---|---|
 | CheckSealed | Checks whether an instance of a statistical function is in an immutable state. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
 | GetEquivalenceKey | Overridden. Retrieves a value that represents the statistical function's unique equivalence key. |
| GetResult | Overridden. Retrieves the result of the statistical function. |
| Initialize | Initializes the statistical function specifying the types in which the values will be accumulated. (Inherited from Xceed.Wpf.Data.Stats.StatFunction) |
| InitializeFromInstance | Overridden. Initializes the properties of the current instance of the same-type statistical function when a new instance of the same function needs to be created. |
| InitializePrerequisites | Overridden. Initializes the prerequisite statistical functions defined by the PrerequisiteFunctions property. |
| IsEquivalent | Overridden. Retrieves a value indicating whether a statistical function is the equivalent of the current function such that both will return the same result for the same set of values. |
| Reset | Overridden. Resets the statistical function to its original state. |
| Validate | Overridden. Validates the statistical function to ensure that it is able to calculate its result. |
