Directions: 

Using the SPSS 2 × 3 ANOVA data file for Module 4 (located in Topic Materials), answer the following questions. NOTE: Helpful hints are provided here for you to use while answering these questions. There is no separate answer sheet/guide to use while doing this assignment. 

What are the two independent variables in this study? What is the dependent variable? 

Why is a two-way between-subjects factorial ANOVA the correct statistic to use for this research design? 

Did you find any errors that the researcher made when setting up the SPSS data file (Remember to check the variable view)? If so, what did you find? How did you correct it? 

Run Descriptive Statistics on the dependent variable data. What do the skewness and kurtosis values tell you about whether the data satisfy the assumption of normality? 

Perform a between-subjects factorial ANOVA on the data. 

What do the results of the Levene's Test tell you about your data? What does this mean in terms of interpreting the outcomes of the ANOVA? 

What do the results of the Tests of Between-Subjects Effects tell you? Was there a significant main effect of Environment on GPA improvement? Was there a significant main effect of Sex on GPA improvement? 

Was there a significant interaction effect of Environment X Sex on GPA improvement? Report the results for each of these questions providing the actual F-value and p value using the following format: F(df1, df2) = ____, p = .___ or if the p is shown as .000, write it as p < .001; an example of this formatting is F(1, 400) = 15.4, p = .02). 

Use eta squared to provide effect size/proportion of variance accounted associated with each F-value. If the F-value for a main effect and/or for an interaction effect is statistically significant, what is the eta squared (?2) value associated with that outcome? 

HINT: 
Report eta squared, ?2; ignore partial eta squared that SPSS can provide. You have to calculate eta squared yourself. It is not given to you by SPSS, but you can use what SPSS provides to calculate it. Eta squared is calculated by using the values in the column headed "Type III Sum of Squares" from the table with the results for Tests of Between-Subjects Effects." To compute eta squared, which would be notated as ?2, take that source's Type III Sum of Squares and divide it by the value for Corrected Total in the same column. For example, if the Type III Sum of Squares for Environment had been 4.5 rather than 4.696, you would divide 4.5 by 14.677 to get the effect size for Environment. If the Type III Sum of Squares for Sex had been 2.0, you also would divide that by 14.677, etc. Interpret these eta squared results for effect size using the following guidelines from Cohen (1988): 
.01 ~ small 
.06 ~ medium 
.14 ~ large 
If the result for the main effect of Environment was statistically significant, what did you find out when you performed post hoc tests (Tukey HSD) to look at possible statistically significant differences in the pairs of means for Environment groups? 

If the result for the interaction of Environment X Sex was statistically significant, what follow up tests did you perform to understand what was going on here? That is, what did you do to find out what was different for males in the various study Environments versus for females in the various study Environments in effects on GPA improvement? What did you learn? 

When you have a factorial ANOVA and the interaction effect is significant, does the researcher give much attention to any significant main effects when interpreting the results of the study? 

Citing the results of your statistical analyses, what is the conclusion you can draw (and support) regarding research question that was posed in this research (see problem statement)? Write a results section for this study that expresses and supports this conclusion. 
HINT: 
Use the sample write-up of the results for the Two-Way Between-Subjects ANOVA example that is in the textbook to see what you should report and how to say it. Just substitute the correct language and values for the analyses you have done for this problem.

SPSS Installation on Learner's PC or MAC 

SPSS Base and Advanced Statistics Modules may be installed on a PC or MAC computer. The combined program is very large so please make sure you have at least 2 GB of available disk space on your computer. Once the program file is downloaded, you may access SPSS software to complete classroom assignments and perform quantitative analysis as related to your own research. Actual installation can be performed in less than five minutes after the file has been downloaded. However, the initial download may exceed 60 minutes if your Internet connection is relatively slow. In some instances when the download exceeds 60 minutes, the download may not complete. Should you experience issues when attempting to download the SPSS file, please access the SPSS Server (below). Please use the following links to obtain installation instructions and the program file:
