Evaluates the effectiveness of 2 different computer assisted instruction (CAI) formats compared with traditional in-class instruction as a laboratory supplement to lectures in introductory statistics. 134 students enrolled in an introductory statistics course in psychology were assigned to 1 of the 3 lab sessions. The evaluation consisted of affective responses to a questionnaire concerning the lab session, as well as student performance on 3 homework assignments and on a midterm examination. Lab format had a significant effect on attitude toward the lab; it did not, however, significantly influence performance. Path analysis revealed relations between lab format, student attitude toward the lab, and performance on the midterm exam.
