A researcher wants to assess if anti-bullying interventions can increase attitudes against bullying in a random sample of 24 8th grade students. She will assess a main effect of gender (male and female), a main effect of intervention (didactic & group) and an interaction effect between gender and intervention. This factorial ANOVA will allow her to study if attitudes against bullying can be increased comparing a didactic method to a group method and assess if there is a difference between males and females on the effectiveness of either method. The Attitudes Against Bullying (AAB) will be used and higher scores reflect higher attitudes against bullying. The researcher conducts a 2 X 2 ANOVA to help in answering the questions.

Please enter and check data carefully. Please use an alpha of .05 for all analyses.

Please complete an analysis to identify if any univariate outliers exist among the scores using the column of scores for the dependent variable. What was the highest positive z-value and highest negative z-value reflecting the scores?
