Describes and evaluates a method for involving large numbers of introductory psychology students as active researchers via an assigned project involving computer analyzed data. Results indicate students valued research more, understood statistical procedures better, and felt less anxious about statistics and computers. Suggests a viable way to…

An iterative least squares procedure for analyzing the effect of various kinds of intervention in time-series data is described. There are numerous applications of this design in economics, education, and psychology, although until recently, no appropriate analysis techniques had been developed to deal with the model adequately. This paper…

The computer programs described in this manual were designed for the analysis of data resulting from psychological experiments which hypothesize an aptitude- or trait-treatment interaction (ATI). The programs were written in Fortran IV for use on most CDC 6400/6600 and IBM 360 computer systems. Research designs to which the programs are applicable…
