Step 1: Write Section 1 of the DAA: The Data Analysis Plan
• Name the variables used in this analysis and whether they are categorical or continuous.
• State a research question, null hypothesis, and alternate hypothesis for the analysis of variance (ANOVA).
Step 2: Write Section 2 of the DAA: Testing Assumptions
Test for one of the assumptions of ANOVA – normality.
• Create SPSS output showing the Shapiro-Wilk test of normality. Run the Shapiro-Wilk test on the dependent variable test for the entire sample. Do not split the data up by gender before running the normality test.
• Paste the table in the DAA.
• Interpret the Shapiro-Wilk test and how you determined whether the assumption of normality was met or violated.
Step 3: Write Section 3 of the DAA: Results and Interpretation
• Paste the following SPSS tables into the document:
o Descriptives table.
o ANOVA table.
o Multiple Comparison table.
• Report the means and standard deviation of quiz3 for each group of the section variable.
• Report the results of the F-test and interpret the statistical results against the null hypothesis and state whether it is accepted or rejected.
• Finally, if the F is significant, interpret the post-hoc tests (multiple comparisons).
Step 4: Write Section 4 of the DAA: Statistical Conclusions
• Provide a brief summary of your analysis and the conclusions drawn about this ANOVA.
• Analyze the limitations of the statistical test and/or possible alternative explanations for your results.
Step 5: Write Section 5 of the DAA: Application
Analyze how you might use this statistical approach in your field for study.
