Rob,

I don't think that the one-way procedure will calculate power for her. However, if you 
have General Linear Model procedure she can use the univariate procedure to conduct 
her one-way ANOVA (it sets up the same way as the one-way) and simply request effect 
size and observed power from the options list. 

Let me know if these directions are not clear.

Best of luck 

Dennis

First, I'd like to thank everyone who responded to the list yesterday with
comments and suggestions for my student (re: marginally significant).

It seems as though the most prudent step is to have her calculate the power.
We have SPSS v.11.0 on campus and I have been encouraging students to use
this for their data analyses, but I can't seem to locate the method for
calculating power for a one-way ANOVA. Is anyone familiar with v.11.0 enough
to instruct me on how to calculate power?

Thanks again,

Rob
