Z-Regression Analysis in Psychological and Educational Researches

Educational achievement of students is closely related to psychological determinants. Information on relation between psychological parameters such as motivation, attention, anxiety and educational achievement of students is naturally characterized by fuzziness and partial reliability. In order to obtain information, we use experiments conducted by using Pilates exercises. The obtained information is formalized by using Z-number concept which allows describing fuzzy and partially reliable information. Thus, we use Z-number valued regression model to describe dependence of educational achievement on motivation, attention, and anxiety. An example is used to show validity of the model.
