For Output Range, choose a cell where you would like the results to appear. Feel free to leave Alpha at 0.05, unless you wish to use a different significance level. The Analysis Toolpak doesn’t have an explicit function to perform a repeated measures ANOVA, but the Anova: Two-Factor Without Replication will produce the results we’re looking for, as we’ll see in the output.įor Input Range, type in the cell range that contains the response times for the patients. ![]() Select Anova: Two-Factor Without Replication and click OK. Once you click on Data Analysis, a new window will pop up. To perform the repeated measures ANOVA, go to the Data tab and click on Data Analysis. If you don’t see this option, then you need to first install the free Analysis ToolPak. Step 2: Perform the repeated measures ANOVA. Perform the following steps to conduct the repeated measures ANOVA in Excel.Įnter the following data, which shows the response time (in seconds) of five patients on the four drugs: Since each patient is measured on each of the four drugs, we will use a repeated measures ANOVA to determine if the mean reaction time differs between drugs. To test this, they measure the reaction time of five patients on the four different drugs. Researchers want to know if four different drugs lead to different reaction times. Example: Repeated Measures ANOVA in Excel This tutorial explains how to conduct a one-way repeated measures ANOVA in Excel. A repeated measures ANOVA is used to determine whether or not there is a statistically significant difference between the means of three or more groups in which the same subjects show up in each group. ![]()
