Fuzzy statistical analysis and estimation

Abstract

In social science research, many decisions, evaluations, or purposes of evaluations are done by surveys or questionnaires to seek for people`s consensus. The commonly used method is asking people to think in binary logic way from a multiple choice design. However, these processes often ignore the fuzzy, sometimes even ambiguous thinking behavior perceived in human logic and recognition. © Springer-Verlag Berlin Heidelberg 2006.
