In the comparative analysis of complex economic phenomena the measures of distance are used to assess similarity of objects. In the paper attention is paid on application of the Bray-Curtis, Canberra and Clark distance measures. Some consequences of strengthening of the measurements scale are also considered.. They appear, among others, when modified distance measures e.g. of Bray-Curtis, Canberra or Clark for data measurements on quotient scale are applied for measurements on the interval scale.
