Stats help (1200 reps)
Will rep helpful responses
say you have 3 conditions:
Full attention
partially-divided attention
fully-divided attention
you conduct an omnibus ANOVA and find that some of the means differ significantly, and have an R-squared value of 0.75
so you decided to conduct a planned comparison, and compare Full attention to partially and fully divided attention combined
you calculate a contrast, get a t value and determine whether the difference is significant
However, my question is: is it possible to calculate a statistical effect size from this?
also, anyone know the correct APA format to describe error bars in a graph (do you just put +/1 SD in one of the title axes...I'll clarify this if its unclear
again, will rep thanks

I'm thinking of taking my t-value...converting it to an F-ratio and using that to calculate a partial eta-squared (or partial r-squared)...anybody approve?

not really about being smart when it comes to stats...its just being exposed to it at some time in your life...I just happen to be auditing a course and helping out the gf with an assignment...thanks again
