Abstract
Description
The study seeks to establish the factor structure, the reliability and validity of Statistics Anxiety Rating Scale (STARS) and the Statistics Anxiety Scale (SAS). STARS and SAS were examined among a sample of Psychology students in four Nigerian Universities comprising 110 males and 150 females with their age rangingfrom 16 to 29 years (M = 20.97; SD = 2.81). Factorial validation of the scales is in consonance with studies by other authors in other countries. Good scorer reliability was observed for both the STARS and the SAS. The Dieting belief Scale (DBS) was used to establish the divergent validity with .09 and -.10 for STARS and SAS respectively. A comparison of score across the sub-scale of STARS showed that mean scores were highest for worth of statistics and interpretation anxiety and lowest on fear of statistics teacher. For SAS, highest mean score was obtained for examination anxiety and lower for interpretation anxiety. Cronbach’s alpha statistics indicates relatively similar findings with those of initial findings of STARS and SAS ranging from .72 to .93.
