Question;SPSS Homework 3 Instructions;One-Way;ANOVA;Part;1;Green;Salkind: Lesson 25, Exercises 1?3;The following helpful tips are numbered to;correspond with the exercise number to which they refer (a dash indicates that;no tips are needed);1.;Use Tukey?s test as the post hoc test for ANOVAs in PSYC 355. Be sure;to check this box when you run analyses. For letters a?d, instead of;identifying these values on your output, as the text states, write them into;your Word file as written answers for;#1 a, b, c, and d. (2 pts for output and 2 pts each for a?d);2.;---------- (3 pts);3.;Remember to put your dependent;variable in the ?variable? box, and your independent, or grouping, variables in;the ?category axis? box. (3 pts);Part;2;1. Sixth grade students who struggle 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.;The steps will;be the same as the ones you have been practicing in Part 1 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. (3 pts);MCBT;39, 32, 36, 33, 32, 37, 37, 38;NMCBT;32, 30, 28, 26, 31, 27, 29, 26;T;25, 31, 24, 26, 26, 30, 27, 25;2. What is the F ratio for;the therapy group main effect? (3 pts);3. What is the effect size;for the overall effect of therapy type on social skills scores? According to;general conventions, is this effect small, medium, or large? (3 pts);4. Write an APA-style Results section describing the outcome. All;homework ?Results sections? must follow the example given in the Course Content;document ?Writing Results of Statistical Tests in Current APA Format? (Note;you do not have to refer to a figure). (3 pts);5. The null hypothesis for this test can;be written as follows: ?There is no difference among the mean social skills;scores across all three therapy conditions.? Based on your results, should this;hypothesis be rejected or retained, and why? Write your answer in sentence;form. (3 pts);Part;3: Cumulative Homework;1. In a study of the relationship;between violent pornography and aggression toward women, 16 male volunteers are;selected and randomly assigned to 1 of 2 groups. One group views a violent;sexually explicit film, and the other group sees a nature film. A test to;measure aggressive feelings toward women is then administered to all;participants. (High scores = high aggressive feelings.) Is there a significant;difference between the groups on feelings of aggression towards women? Choose;the correct test to analyze this question, set up the SPSS file, and run the;analysis. Follow the directions under the table below.;Nature Film;4;5;7;9;6;4;2;3;5;Explicit Film;6;8;5;11;10;7;7;a);Paste appropriate SPSS output.;(3 pts);b);Paste appropriate SPSS graph.;(3 pts);c);Write a Results section in;current APA style describing the outcome. All homework ?Results sections? must;follow the example given in the Course Content document ?Writing Results of;Statistical Tests in Current APA Format? (Note: you do not have to refer to a;figure). (3 pts);Submit this assignment by 11:59 p.m. (ET);on Monday of Module/Week 3.
