PSYC 355 SPSS HOMEWORK 3 INSTRUCTIONS ONE-WAY ANOVA Part One: 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 ANOVA's 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, please write them into your Microsoft Word file as written answers for #1 a, b, c and d. (2 pts for output; 2 pts each for a-d) Note: letter d refers to the results of Levene's test (see SPSS tutorial presentation for review) 2. The effect size is found in the SPSS output. Review section on effect size statistics in this lesson. (3) 3. Remember to put your dependent variable in the \"variable\" box, and your independent, or grouping, variables in the \"category axis\" box. (3) Part Two: 1. Twenty-four adults who have been diagnosed with an adjustment disorder are randomly assigned to one of three group therapy conditions in order to improve their coping skills: manualized cognitive-behavioral therapy (MCBT), non-manualized cognitive-behavioral therapy (NMCBT), and talk therapy (T). Following two months of therapy, the participants are assessed on a standardized measure of coping skills. On this instrument, scores range from 0-45, and higher scores indicate better or improved coping skills, while lower scores indicate coping 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 coping skills. The steps will be the same as the ones you have been practicing in Part One of the assignmentthe 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.

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) 4. Write a current APA-style Results section based on your analysis. All homework \"Results sections\" should follow the example given in the SPSS tutorials and the Course Content document \"Writing Results of Statistical Tests in Current APA Format\" (note: you do not have to refer to a figure). Remember to include a decision about the null hypothesis. (3) Part 3: Cumulative Homework 1. A researcher wanted to investigate whether there was a difference in satisfaction ratings in an assisted living facility between residents who attended daily activities and those who did not. Due to relocations during the study, 3 participants were dropped from the \"No Daily Activities\" group. The researcher then administered a scale asking them to rate their overall satisfaction with the facility. Did attending daily activities have an impact on the residents' overall satisfaction levels? Choose the correct test to analyze this question, set up the SPSS file, and run the analysis. Follow the directions under the table below.

All homework \"Results sections\" should follow the example given in the SPSS tutorials and the Course Content document \"Writing Results of Statistical Tests in current APA Format\" (note: you do not have to refer to a figure). Remember to include a decision about the null hypothesis. (4) Submit this assignment by 11:59 p.m. (ET) on Monday of Module/Week 3. Page 3 of 3
