Problem Set 1: One-way ANOVA

Research Scenario: Twenty-four male adolescents who have been diagnosed with conduct disorder with a callous-unemotional presentation (CD-CU) are randomly assigned to one of 3 group therapy conditions: interpersonal problem-solving skills training only (IPST), parent training only (PT), and a combination of the two (IPST + PT). Following six months of therapy, the participants are assessed using the Inventory of Callous Unemotional Traits (ICU; Frick, 2004). On this instrument, scores at or above 27 indicate higher levels of conduct problems and callous-unemotional traits. The scores for each group are shown in the table below. Conduct a one-way ANOVA to determine whether there is a significant difference in ICU scores between the three therapy conditions.

(The steps will be the same as the ones you have been practicing in Part One of the assignment-the only difference is that you are now responsible for creating the data file as well. Remember to name and define your variables under the "Variable View," then return to the "Data View" to enter the data.)

IPST

30, 25, 26, 31, 29, 24, 32, 35

PT

29, 21, 28, 32, 25, 27, 29, 30

IPST + PT

19, 19, 24, 30, 26, 23, 27, 28

above is the pro the problem but my question is how do i enter this data into spss to get the correct information
