The following data sets are from a factorial design study examining the effects of group and individual therapy over two different lengths of time. For each data set, determine what effects (both main effects and interaction) are significant. For simplicity, assume that the data are ideal, meaning that any difference between means is a significant difference- no sampling error. Make a bar graph of each significant effects and provide a verbal description of the effects.
