anyone here a statistic wiz?
    #10918253 -

I need someone to help me understand Tukey and how the calculation helps to calculate confidence interval for all paired differences and gives increased simultaneous confidence degree.

I'm supposed to do an ANOVA using Tukey's method. n=4 N=20
I could post the actual set of data if that'd help you get the question.

the task is:
Find out how you, with Tukey's method, can calculate confidence interval for all paired differences between treatment-effects so that you get a desired simultaneous confidence grade.

Thanks but those handle mainly matched sets while my problem is not matched.
Also they do not discuss the difference between standard ANOVA and applying Tukey's method.

I'm digging through old course material, maybe I'll be able to figure this out..

I'm fairly certain the Tukey is a post-hoc test, done after the initial ANOVA to determine where significant differences lie.

I assume you found the wiki already, but if not:

Yeah.
What I need is to figure out how to decide the simultaneous confidence grade.
I think I need to look over the data from my minitab project, I think it should be there.
I'm more than a bit rusty, havent done anything like this for one and a half year.
