Is the following possible:

I have repeated measures data (reaction times) that has 5 levels and different numbers of responses per level (5-20-5-20-50). The number of responses (correct responses only) may vary within the levels (that is there are circumstances where there is 'missing' data).

Is it possible to get SPSS (or any other analysis package) to do an analysis with the actual data (so that I can also attend to possible variance differences). Or, as it seems to be, must I use means of the 5 different levels and forego any more thorough analysis.

Any help and information is greatly appreciated.

Thanks in advance,
