SPSS Exercise – Running ANOVA Tests

The most effective way to gain a better understanding of statistics is to run statistical tests and interpret the results.

In the following SPSS exercises, you will run two different types of analysis of variance (ANOVA) tests:

• One-way ANOVA.
• One-way repeated measures ANOVA.

Refer to the ANOVA Exercises document, listed in Resources, to complete these exercises. The ANOVA Example might also be useful to review.

SPSS Exercises

Exercise 1: One-way ANOVA

• Use the data file stroke_clean.sav located on your computer in your SPSS folder. (Recall that these files were installed on your computer when you installed SPSS).

Exercise 2: One-way repeated measures ANOVA

• Use the data file diet_study.sav located on your computer in your SPSS folder.

The results from both of these exercises are required to complete the discussions in this unit.

Contrasting ANOVA and t-test

The ANOVA allows you to compare multiple levels of data.

• Discuss the findings of the analyses you did in the ANOVA study exercises in this unit, and what advantage(s) they have over the t-tests.
• Include the results of the tests in your post.

Response Guidelines

Learning Components

This activity will help you achieve the following learning components:

• Practice interpreting statistical data.
• Demonstrate statistical literacy by using correct statistical terminology.
• Expand your statistical vocabulary.

Personal Reflections on ANOVA

What is an example of something in your life where you might be able to impart better understanding by doing a study based on an ANOVA design (either independent or repeated)?

• Describe your test variable and what you hope to learn as a result of running a statistical test.
