American Educational Research Association Annual Meeting,


EncStat (Encouraged about Statistics) is a multimedia program being developed to identify and assist students with statistics anxiety or negative attitudes about statistics. This study explored the validity of the assessment instruments included in EncStat with respect to their diagnostic value for statistics anxiety and negative attitudes about statistics and conducted a pilot study of a weekly attitude change tracking instrument. Data from 69 graduate students supported the psychometric integrity of the Survey of Attitudes towards Statistics (SATS; Schau, Stevens, Dauphinee, and Del Vecchio, 1995) and the Statistical Anxiety Rating Scale (STARS; R. Cruise, R. Cash, and D. Bolton, 1985) and their revised, combined version. The Study Skills assessment and the Past Math History assessment developed for the EncStat program were also evaluated and supported. The Statistics Anxiety Weekly Affect Check, which evaluated 23 emotions in 7 areas related to statistics, was analyzed through 998 affect responses over a semester. Exploratory factor analysis identified the factor structure of the scale, and internal consistency estimates were acceptable. Findings also supported the mathematics diagnostic scale developed for use at the beginning of statistics courses. Findings suggest the statistics anxiety surveys targeted for EncStat will support reliable decisions in the program without undue burdens on students. The affect check is attached.
