Twenty-four computer programs were developed to supplement a course in statistics required of psychology majors. Thirteen are tutorial in nature. The rest provide the user with sample measures and demonstrate solution of a statistical problem (e.g., finding the product-moment correlation). Part of a CAUSE project to increase science literacy and reduce mathematics anxiety, the programs' effectiveness were evaluated in an elaborate testing program. Results showed that, as in the case of other science programs developed, using the statistics programs was not followed by a decrease in anxiety, hostility, or depression. An increase in those variables correlated very highly with increased proficiency in statistics. It was concluded that the supplemental programs enhanced students' coping skills which enabled them to turn negative emotions into constructive motivation. (Author)
