Parameters

sample IReadOnlyListDouble: The sample.

Return Value

Interval
The interquartile range of the sample.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IReadOnlyListDouble. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

The interquartile range is the interval between the 25th and the 75th percentile. Statistics textbooks define this range as the width of this interval, but since we have to compute the endpoints to get the width, we return the full Interval.
