# Identify an appropriate research question that would require the use of a factorial or mixed-design ANOVA to answer.

## Complex ANOVA Study

Background

During this week you will identify a research question created in Week 1 that would utilize one of the following: factorial ANOVA or mixed-design ANOVA. If there are no research questions that fit any of these types of statistical analyses, you will need to decide on a new question before moving forward with the assignment.

Initial Posting – In your initial posting for this assignment, include the following:

Discussion Assignment Requirements

• Identify an appropriate research question that would require the use of a factorial or mixed-design ANOVA to answer. Pick the question from the list created in Week 1 or identify a new question if there are no appropriate ones from Week 1.
• Describe why this question is appropriate for the selected statistical test.
• Identify the variables in this study and each of their attributes: discrete or continuous, quantitative or categorical, scale of measurement (nominal, ordinal, interval, or ratio), and independent or dependent.
• Do the variables fit the qualifications for the selected statistical test? Explain.
• List the statistical notation and written explanation for the null and alternative hypotheses.
• Describe the types of errors that could occur.

Replies – Though you may respond to your peers multiple times during the week to provide support or feedback, students are required to respond to one of their classmates’ postings by Day 7.
