Niektóre metodologiczne problemy występujące w diachronicznej analizie porównawczej wyników sondaży

Abstract

Selected results of two surveys conducted in 1977 and 1984 among the adult population of the city of Łódź were compared aiming at the demonstration of two kinds of problems: 1) those related with the construction of a replicated sample in 1984; 2) those related with historical incomparability of the meaning of certain questions asked in two different socio-political contexts. It was also ascertained that in 1984 respondents were generally much more reticent in their replies to open-ended questions - especially white coller workers and pensioners. A method of recalculation of percentages of certain replies in 1984 to make them more comparable with higher percentages obtained in 1977 is proposed.
