The article shows the use of statistical methods of multivariate analysis on the example of environmental data – the species composition of terrestrial arthropods. It is shown that the research results largely depend on the scale of observations made – whether it is a study conducted in a whole ecosystem or in a separate landscape element, type of habitat or, finally, an analysis of elementary samples. The results and their interpretations directly depend on the scale chosen by the researcher. We were mainly concerned with the reliability of using of multidimensional statistics in practical situations.
