1 Computer assignment 4 Summer 2014 Online 20 points Assume that a statistical consultant has been called in to assist the police department of a large city in evaluating its human relations course for new officers. The independent variables are type of beat to which the officers are assigned during the course, treatment A, and the length of the course, treatment B. Treatment A has three levels: upper-class beat, a1, middle-class beat, a2, and inner-city beat, a3. Treatment B also has three levels, 5 hours of human relations training, b1, 10 hours, b2, and 15 hours b3. The dependent variable is attitude toward minority groups following the course. A test developed and validated previously by the consultant is used to measure the dependent variable.

Source Beat Hours Beat x Hrs Error SS df MS F 2 1. If the Main Effect of Beat is Significant conduct subsequent pairwise comparisons using Tukey and LSD.If it is not significant state that below. Make sure I can easily see what the critical difference(s) are. Write your specific conclusions below. 2. If the Main Effect of Hours is significant conduct subsequent pairwise comparisons using Tukey and LSD.If it is not significant state that below. Make sure I can easily see what the critical difference(s) are. Write your specific conclusions below. 3 3. If the Interaction of Beat x Hours is significant conduct subsequent pairwise comparisons Tukey and LSD. If it is not significant state that below. Make sure I can easily see what the critical difference(s) are. Conduct the pairwise comparisons so you can investigate the effects of hours of training separately for each Beat.
