In this assignment, you will compare and contrast the various versions of ANOVA.

Part 1

Using the week’s resources as well as those you locate yourself, define and describe the following variance analysis tools:

• one-way ANOVA,
• ANCOVA,
• MANOVA, and
• MANCOVA.

Part 2

Find two research studies (peer-reviewed journal articles) that each used one of these tools (e.g., one article about one-way ANOVA and another about MANOVA). Very briefly summarize each study. Then compare and contrast the two articles identifying, specifically, the type of hypothesis(es) the tools were used to investigate, etc.
