with similar social difficulties at school and home are randomly assigned to 1 of
3 group therapy conditions in order to improve their social skills: manualized
cognitive-behavioral therapy (MCBT), non-manualized cognitive-behavioral
therapy (NMCBT), and talk therapy (T). Following 2 months of therapy, the
students are assessed on a standardized measure of social skills. On this
instrument, scores range from 0 65, and higher scores indicate better or
improved social skills, while lower scores indicate social skills that need
improvement. These scores are shown in the table below. Conduct a one-way ANOVA to determine how effective these 3 therapy
conditions are at improving social skills.
