Using the Repeated Measures ANOVA Function
The Repeated Measures ANOVA function in EZAnalyze allows you to conduct a statistical hypothesis test on more than two group means. Since this is an Advanced feature of EZAnalyze, it will not be discussed at length here. Feel free to consult a statistics textbook or the Internet for information on what Repeated Measures ANOVA is and how it works. If you are already familiar with Repeated Measures ANOVA and want EZAnalyze to crunch the numbers for you, read on!
To ensure that your data is ready for a Repeated Measures ANOVA, make sure that you have at least two variables for use in this procedure that are 'on the same metric'. SO, for example, if you wanted to see if students' GPA varied from quarter to quarter, you would need to have data for at least two quarters.
To perform a Repeated Measures ANOVA on your data, select "Advanced" from the EZAnalyze menu in Excel, and then choose "Repeated Measures ANOVA" .
When the "Repeated Measures ANOVA" dialog box appears, select your variables from the list provided, then click OK.
When you click OK, a results report will be printed on a separate sheet for your review. (click on "results report" for information on how to interpret this analysis)
