ANOVA Application and Interruption 4

ANOVA APPLICATION AND INTERPRETATION

Instructions

Complete the following for this assessment:

· For this assessment, you will use the Data Analysis and Application Template (DAA Template [DOC]).

· For help with SPSS, refer to IBM SPSS Step-By-Step Instructions: One-Way ANOVA [DOC].

· For help copying SPSS output into your DAA, review the Copy/Export Output Instructions [HTML].

· For information on the data set, you may find the Data Set Instructions [DOC] helpful.

· Refer to the 7864 Course Study Guide for information on analyses and interpretation.

This assessment is on ANOVA. You will analyze the following variables in the grades.sav data set:

SPSS Variable	Definition
Section	Class section
Quiz3	Quiz 3: number of correct answers

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:

. Descriptives table.

. ANOVA table.

. 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.

· Name an independent variable (the IV should have three or more groups/categories) and dependent variable that would work for such an analysis and why studying it may be important to the field of practice.

Submit your DAA Template as an attached Word document in the assessment area.

Software

The following statistical analysis software is required to complete your assessments in this course:

· IBM SPSS Statistics Standard or Premium GradPack, version 24 or higher, for PC or Mac.

You have access to the more robust IBM SPSS Statistics Premium GradPack.

Please refer to the Statistical Software page on Campus for general information on SPSS software, including the most recent version made available to Capella learners.

Make sure that your SPSS software is downloaded and installed with fully activated licensing on your computer and running properly within your operating system (PC or Mac). If you need help with these steps, refer to the SPSS Installation Helper.
