Abstract

This study investigates the effect of achievement in statistics to students’
attitude toward statistics using the Adaptive Neuro-Fuzzy Inference System
(ANFIS). Attitude toward statistics is
obtained by means of a statistics attitude scale, and achievement in statistics
is assessed by the midterm exam grades of the students. For fuzzy clustering
membership function is selected to be triangular and subtractive clustering is
used. As a result of clustering, three fuzzy clusters are obtained for
statistical achievement, which are named unsuccessful/ moderate/successful. The
model established from ANFIS showed
that the attitude of students receiving low achievement grades in statistics is
negative and that attitude is more positive as the achievement increases. This
study also showed that fuzzy methods are used successfully in social sciences.
