Complete questions 1, 14, and 21. Use SPSS, a calculator, or spreadsheet to complete the statistical portions of the questions.
Your response to question 1 should be in the form of a short paragraph (3–5 sentences).
- How does the denominator of the \(F\) -ratio (the error term) differ for a repeated-measures analysis of variance compared to an independent-measures ANOVA?
For question 14, your response should replicate the table provided in the question, as well as a brief discussion of what the ANOVA means regarding the outcome of the experiment.
14. The following summary table presents the results of an ANOVA from a repeated-measures experiment comparing four treatment conditions with a sample of \(n=10\) subjects. Fill in all missing values in the table.
For question 21, respond as outlined in the question.
21. Most sports injuries are immediate and obvious, like a broken leg. However, some can be more subtle, like the neurological damage that may occur when soccer players repeatedly head a soccer ball. To examine long-term effects of repeated heading, Downs and Abwender (2002) examined two different age groups of soccer players and swimmers. The dependent variable was performance on a conceptual thinking task. Following are hypothetical data, similar to the research results.
- Use a two-factor ANOVA with \(\alpha=.05\) to evaluate the main effects and interaction.
- Briefly describe the outcome of the study.
SPSS Assignment
Questions are often asked related to the issue of school size. A researcher in the Department of Education is interested to know if there are distinct regional patterns in school size, as measured by the number of classrooms. Using the SPSS data file frss79spec.sav (See Attached File)
State the null and alternative hypotheses for testing the question: Is there a significant difference among the northeast, southeast, central, and west regions on question 1, total number of rooms in the surveyed schools?
- Determine and conduct the appropriate statistical test. State the test you chose and why.
- Copy or copy object and paste the relevant SPSS analysis.
- State whether you accept or reject the null hypothesis based on the analysis, using appropriate conventions to present your conclusion.
- Briefly explain if there are differences between the four regions and whether they are significant or not.
(Hint: Although this week focused upon repeated measures ANOVA, this question does not.)
