Introduction This site provides illustrative experience in the use of Excel for data summary, presentation, and for other basic statistical analysis. How to perform factorial ANOVA in Excel, especially two factor analysis with and without replication, as well as contrasts. One of the assumptions of repeated measures ANOVA is called sphericity or circularity (the two are synonyms). Here is the table of sample data from Prism 5 (choose a. There are two ways to run a repeated measures analysis.The traditional way is to treat it as a multivariate test–each response is considered a separate variable.The.

The software is available either as a. Zip- compressed file or a raw executable. You only need to. Between- groups ANOVAAs a first example, consider that we collect data examining. We. measure the words- per- minute a participant can type.
What is the difference between Clustered, Longitudinal, and Repeated Measures Data? You can use mixed models to analyze all of them. But the issues involved and some. Action Research & Action Learning A collection of papers which support an online course on action research and evaluation.
Each of the. 1. 5 participants is tested in only one of three conditions: in a. Bach's classical music is played, in a room where. Start by launching. ANOVA icon). Then choose. Describe design' from the data menu.
You will be shown the designwindow like the one shown by the red '1' in the figure on. This experiment has one factor between subject factor: the sound in the room. So. choose '1 Between Subject Factor' from the design pull down menu. Set the levels for Factor A and Factor to three: this.
You may want to name thie factor 'sound' and name the levels 'Bach', 'Rock' and 'Silence'Set the . Enter the values for each particpant by. Note that the first column is labeled.
Choose 'Save' from the. File' menu to save your data to disk. When you are done entering values, press the 'Sigma' button. Note that the top of the window shows an ANOVA. The factor 'Sound' is not significant (the. Choosing 'Copy' from the 'Edit'.
Excel or any other. Within- groups ANOVAIn the previous (between groups) example, each participant was.
For example, Alice was only. Bach, and in no other situations. Note that. some people are much better typists than others. Therefore. individual difference may be adding a lot of variance to our. Since we only tested 5 people in our study, it has very.
One way to. increase the statistical power is to test the same individuals in. That way, we can take into account the. Again, lets consider a hypothetical experiment. The design is. similar to the between- subjects condition, except that we only. The. data is shown below. Note that Nick is pretty slow in all. Sandra is. generally a fast typist (never slower than 5.

Note that if you have already analyzed the. Describe design' from the 'Data' menu of the. Design pull- down menu to '1 Within Subject Factor'. In our. example, the first row of data are the typing speeds for Alice. Bob, etc. Once you have described the design and entered the data. Calculate ANOVA' from the Data Entry Window's 'Data'.
The resulting results should look similar to those. Inspection of this figure shows that there is a significant. ANOVA reports. a P value of . Because the. ANOVA looks at all 3 levels of your experiment, you probably want.
Multifactorial ANOVAOne of the powerful aspects of ANOVA is that you can tease. My software. allows you to analyze up to three factors, with either between or.
Lets consider a hypothetical experiment where we are. We have 2. 0 participants, half.
Half of the members of each of these groups is given a. Therefore, there are a total of two factors. AM versus. PM test time, caffeinated versus decaffeinated coffee). Note that. each individual only takes the test once (it is a between groups. The figure shows each stage for analyzing this data.
We begin. by using the Design window to describe setup of. Next we use the Data entry window. In this example, we find that the. However, we. do find an interaction. In this case looking at the pairwise. This software can also show you a graphical image of.
Once you are in the results window, you can. Line Graph' from the 'View' menu. You will be. shown a graph of the mean results for each condition with. You can customize the. In fact, you can copy or save these images to. EMF' format) so you can edit the. Microsoft Word or many other programs.
This. graph is a vector- based graphic, so it should not appear. Note that you can. ANOVAs, and that.
Another option is to. Results Window into a program that. For example, consider if we wanted to test the fuel economy of a hybrid car versus a version of the car with a conventional motor. In this case, the cars wil be between subjects - we comparing different cars. However, we might want to include a between subject factor such as performance in the city versus highway mileage. We could reduce some of the variability between individual cars by using the same car in both settings. The steps for creating a mixed design are: Launch ez.
