IStatisticsResults Interface

Provides access to members used for reporting statistics.

Description

IStatisticsResults is implemented by the BaseStatistics object and also by the histogramobjects (see esriCartoUI). Its use is straightforward, the only point to note is for the StandardDeviation property�if your data is a sample of the real data, you should indicate so with IGenerateStatistics::Sample before calling StandardDeviation.

IStatisticsResults.StandardDeviation Property

The standard deviation, based on sample flag.

Public ReadOnly Property StandardDeviation As Double
public double StandardDeviation {get;}

Description

Returns the StandardDeviation of all the data values in the BaseStatistics.
