Note: You will use a new data set this week, which you will need to download. You will conduct a regression analysis using the following variables in the anxiety.sav data set:
• Anxiety.
• Exam.
Step 1: Write Section 1 of the DAA – the Data Analysis Plan:
• Briefly describe the goal of your analysis.
• State your research question, null, and alternate hypothesis.
• Specify the variables used in this analysis (predictor, outcome) and the scale of measurement of each variable.
• State the sample size (N) and the alpha level you will use (.05 unless otherwise specified).
• Explain why the analysis is a good choice based on the nature of your variables.
Step 2: Write Section 2 of the DAA – Testing Assumptions:
• Articulate and test the assumptions of regression.
• Paste the SPSS model summary into the assumptions section of the DAA Template and interpret the Durbin Watson statistic..
• Report whether any outliers were found in the data.
• Paste the scatter plot of standardized residuals and interpret it for homoscedasticity.
• Paste the histogram and SPSS Normal P-P plot into the DAA Template and interpret it.
• Summarize whether or not the assumptions of regression are met. If assumptions are not met, discuss how to ameliorate violations of the assumptions.
Step 3: Write Section 3 of the DAA – Results and Interpretation:
Step 3: Write Section 3 of the DAA – Results and Interpretation:
• Paste the SPSS output of the model summary.
• Paste the SPSS ANOVA output and report the results of the F test for the model.
• Paste the SPSS coefficients data.
• Provide results for F, Degrees of Freedom, F Value, R2, β, and the effect size: Cohen’s f2.
• Interpret statistical results against the null hypothesis and state whether it is accepted or rejected.
Step 4: Write Section 4 of the DAA – Statistical Conclusions:
• Provide a brief summary of your analysis and the conclusions drawn.
• Analyze the limitations of the statistical test.
• Provide any possible alternate explanations for the findings and potential areas for future exploration.
Step 5: Write Section 5 of the DAA – Application:
• Analyze how you might use this statistical approach in your field and what the potential implications would be.
