THE ANALYSIS OF CONSISTENCY OF EMPIRICAL NORMATIVE VALUES FOR FINANCIAL RATIOS AT DIFFERENT LEVELS OF AGGREGATION OF COMPANIES LISTED ON THE WARSAW STOCK EXCHANGE

Summary/Abstract: The article presents results of the research that aim was to examine to what extent the empirical norms computed at different levels of object’s aggregation differ from each other and from the theoretical norms. The study was based on statistical data on three financial ratios that characterize liquidity, activity and debts of companies that were listed on the Warsaw Stock Exchange in 2011. The classical and positional ranges were used as the empirical ranges of normative values because the selected ratios are nominants. Mean, standard deviation, median and median absolute deviation were used in order to compute them. The aggregations of companies were made at the following levels: sectors (the lowest level), macrosectors, macrosectors jointly (the highest level).
