The first ten rows of our dataset Preparing the Repeated Measures FactorPrior to executing our analysis, we must follow a small series of steps in order to prepare our repeated measures factor.

> #notice the atypical column arrangement for repeated measures data Example 3: Two Way ANOVA without Replication in EXCEL An experiment is conducted to determine whether the brand of laundry detergent used and the water temperature affects the amount of dirt removed dirty laundry, and following data is collected (see worksheet LAUNDRY DATA of file 2Way ANOVA in Excel.xlsx).

> #read the dataset into an R variable using the read.csv(file) function.

Hence, rather than having one vertical column for voting interest, with a second column for age, we have three separate columns for voting interest, one for each age level.Д«eginning StepsTo begin, we need to read our dataset into R and store its contents in a variable. In a repeated measures ANOVA, we instead treat each level of our independent variable as if it were a variable, thus placing them side by side as columns. In a typical one-way ANOVA, we would place all of the values of our independent variable in a single column and identify their respective levels with a second column, as demonstrated in this sample one-way dataset. The interest values are represented on a scale that ranges from 1 to 5 and indicate how interested each participant was in voting at each given age.Дata SetupNotice that our data are arranged differently for a repeated measures ANOVA. This dataset contains a hypothetical sample of 30 participants whose interest in voting was measured at three different ages (10, 15, and 20).

This tutorial will demonstrate how to conduct one-way repeated measures ANOVA in R using the Anova(mod, idata, idesign) function from the car package. When it is finished, click on the Data tab and the Anova Data Anaylsis function will appear in the Anaylsis group on the right side of the ribbon.Repeated measures data require a different analysis procedure than our typical one-way ANOVA and subsequently follow a different R process. This can take a minute or two to configure. (If you do not have Data Analysis in your Tools menu, see the first Excel help page linked to our courses index page.) The screens. This function is available in the Tools menu under Data Analysis. The Microsoft Office Configuration window will launch. Here are two screen shots from the Excel spreadsheet program, the result of using Excels built-in ANOVA Single Factor function on the data above.
