A bifactor model for the Scale of Attitudes towards Statistics

Abstract

The objectives of the study were to determine the psychometric properties of the Scale of Attitudes towards Statistics in Mexico. In this instrumental study, a non-probabilistic sample of 383 Mexican psychology students who responded to two attitude scales was analyzed. The bifactor model with three specific factors (safety, pleasure-usefulness, and motivation) showed the best properties of fit and convergent validity. The average attitude was neutral and more positive in men than in women. The general factor had a high correlation with attitude towards research. It is concluded that the three-factor bifactor model represents the relationship between the items better than the original five-factor model.
