Resumen

In this paper some methods commonly used in multivariate cluster analysis are discussed and compared byusing a specific data set. The main objective is to show that the graphical method is efficient and similar tothe Ward and K-Means methods which are based upon mathematical and statistical theories. Thesimilarityfound between the graphical and the statistical methods suggests that although it is more subjective thegraphical method is a valid technique that could be used to determine the clusters of a sample or a population.,
