Re: error estimate as fraction of standard deviation

This sounds like homework but I will . Anyway assume the normal approximation to the binomial can be used (is this reasonable?) then the formula for estimating sample sizes based on a given confidence level and a given maximum error is n = z*Sqrt(p*(1-p))/e where z = the z-scores associated wit

Re: adjusted r-square

In short, you don't. If the number of terms in the model equals the number of observations you have much bigger problems than not being able to compute adjusted R^2. It should always be the case that the number of observations exceed the number of terms in the model otherwise you cannot calculate

Re: SPSS GLM - between * within factor interactions

I'm not sure if this will work for your experiment but have you tried respecifying the model in terms of a nested design. Using syntax you can type A(B) in the DESIGN subcommand which means A nested within B. The code example below would fit the model Y = Constant + A+ B(A) UNIANOVA Y BY A B
