In this paper the rule of excluding observations based on \(Q1 – 1.5Q\; Q3 \+ 1.5Q\) interval is investigated, for data from household budget survey in 2011, for Polish voivodeships. It is shown that although including more observations obviously changes the values of inequality measures, the relative values of them are surprisingly quite stable, with the rank correlation coefficient never over 0.9"]
