Question

PSYC 355;SPSS HOMEWORK 3 INSTRUCTIONS;ONE-WAY ANOVA;Part 1;Green & Salkind: Lesson 25, Exercises 13;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 Tukeys test as the post hoc test for ANOVAs in PSYC 355. Be sure to check this;box when you run analyses. For letters ad, 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 ad);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);Page 1 of 2;PSYC 355;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;Explicit Film;4;5;7;9;6;4;2;3;5;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.;Page 2 of 2
