Microsoft Word - HW1_r2_.doc PY520XA/ZA[Type here]Summer 2019 Data Analysis 4 · Type your answers as much as possible. Copy and paste only essential parts of output for your answers. · Plagiarism on the homework will results in an automatic 0 and referral to the Academic Dean. Plagiarism is grounds for an overall grade of zero in the course. In this homework, you will use an SPSS data file, hsb.sav. It is uploaded in data folder in module tab on Canvas. Therefore, you can download from the course website. 1. We are interested whether the Motivation (mot) is different among three levels of social economic status (ses). a. State the null hypothesis (H0). b. Using SPSS One-Way ANOVA procedure, conduct the analysis. Request descriptive statistics, homogeneity of variance test, and Welch’s adjusted statistics. Attach the output tables. 2. Let’s examine the first table. a. What are the sample sizes for the three samples? b. What are the means for the three samples? c. What are the standard deviations for the three samples? 3. Let’s examine the One-way ANOVA result. First, look at the result when we assume the equal-variance assumption is met. a. What is the p-value? Interpret the p-value, based on the definition. b. What is your decision about H0? c. Interpret your decision in b, in the context of the problem. 4. Now, let’s look at the result when we assume the equal-variance assumption is violated. a. What is the p-value? b. What is your decision about H0? c. Interpret your decision in b, in the context of the problem. 5. Let’s examine the Levene’s Test result. a. What is the null hypothesis to be tested in this Levene’s test? b. What is the p-value for this Levene’s test? c. What is your conclusion about the equal-variance assumption on this data? 6. Conduct Tukey’s procedure for pairwise comparisons. a. Attach the output table. b. What are the p-values for the 3 pairwise comparisons? c. What is your conclusion about the mean differences among the three social economic status groups? In your answer, reflect results from both the omnibus test and pair-wise comparisons. 1 HSB idsexracesessctyphsplocusconcptmotcarrdgwrtgmathsciciv 1211130.290.880.67103444403941
