Multiple Ways of Processing in Questionnaires

Abstract

In social sciences when questionnaires are used, there is a new tool, the bar instead of Likert scale. The bar has been suggested by Vougiouklis & Vougiouklis in 2008, who have proposed the replacement of Likert scales, usually used in questionnaires, with bar. This new tool, gives the opportunity to researchers to elaborate the questionnaires in different ways, depending on the filled questionnaires and of course on the problem. Moreover, we improve the procedure of the filling the questionnaires, using the bar instead of
Likert scale, on computers where we write down automatically the results, so they are ready for research. This new kind of elaboration is being applied on data obtained by a survey, studying the new results. The  hyperstructure theory is being related with questionnaires and we study the obtained hyperstructures,
which are used as an organized device of the problem and we focus on special problems.
