I have information on 7 treatments, x,  and am assessing their effects. If I have the means and standard deviations of the outcome measurement, y, along with the numbers of observations for each treatment, n, how can I calculate the sum of squares for the error and for the treatment effects?

I would run the data through PROC GLM.

I do not have the data; this is an unusual scenario.

Then you find the ANOVA formulae in some text book (or at Wikipedia) and plug in your means and standard deviations into the formulae.

What is ANOVA?
