(PKPM) The purpose of the present study is to investigate evidence of the validity of Survey of Attitudes Toward Statistics Scale (SATS) scores and their relationship with scores from two other measures of attitudes toward statistics, the Attitude Toward Statistics Scale (ATS) and the Statistics Attitude Survey. The pre- and postcourse responses of 342 graduate and undergraduate students enrolled in inferential statistics courses at a large midwestern university were analyzed. Internal consistency reliability estimates were greater than .90 for total scores and greater than .70 for subscale scores for all instruments. Regression analyses confirmed the importance of SATS subscale scores over and above demographic variables in a theoretical model predicting statistics course achievement. Factor analyses suggested that both the ATS and the SATS have two domains, which is contrary to the four-factor solution proposed by the developers of the SATS.
