Hi!
I'm trying to do a two-way ANOVA test where I have Factor A with 2 levels and Factor B with 3 levels. For all combinations I have a different number of measurments (e.g. A1B1 n=13, A2B1 n=18 ...) and if I run the test with indexed data, it works fine. Yet, I'd like to run the test on raw data where I have the data in 6 seperate columns for all the factor combinations as the indexing is a rather elaborate copy-paste work. When I use the raw-data input mode and select the columns (or only the cells with data), I get the error message: Data do not follow balanced design. Every cell must have one and only one data element.
When I get'balanced design' then I don't think that I need balanced design for this kind of test (it also works with the indexed data).
This restriction/message you are encountering was there in version 8.0. It was removed/fixed in versions 8.1 onwards.
You can download the 8.5 demo and give it a try with your data.
Also in latest version 8.5.1 which is due to be released soon, we have added Stack and Unstack tools for rearranging data from indexed to raw and back. One of these tools existed in 8.5.0, but we improved it as well in upcoming 8.5.1
