Statistics

Description

The mode of a data sample is the element that occurs most often in the collection. For example, the mode of the sample [1, 3, 6, 6, 6, 6, 7, 7, 12, 12, 17] is 6. Given the list of data [1, 1, 2, 4, 4] the mode is not unique, unlike the arithmetic mean.

Example

Calculate the mode of sample data [1,5,2,11,5,3].

var a: Vector;

  a.SetIt(false,[1,5,2,11,5,3]);
  Md := Mode(a); // Md = 5
end;

  a.SetIt(false, OPENARRAY(double,(1,5,2,11,5,3)));
