The necessity of each kind and the distinctions between how to use them, followed by the calculation methods, are shown through specific examples.\nVia geometric interpretations of the four types of mean, the inequality relations between them are clarified.Moreover, by the general definition of mean and the expression of the generalized mean, common features of every type and unique properties of each type are made explicit.
