This paper describes cluster analysis and its application to the base of diabetics divided according to degree of the disease. Cluster analysis involves grouping elements into clusters so the elements within one cluster are the most similar. For clustering we must first define the distance (similarity) between two elements and then define the grouping algorithm. There are hierarchical and nonhierarchical clustering. In described example there were 13 variables measured from which was expected that patients will be grouped into four clusters (healthy, type I diabetes, type II diabetes, prediabetes). Hierarchical clustering was made with the Euclidian distance and the average method, the Gower distance and the Ward method and the Manhattan distance and the maximum method. Also, nonhierarchical clustering was made with k-means algorithm for k=4 and 3.
