Now I know that i have to use P = 0.05, but dont know why! (some site told me it is the least acceptable value- didn't understand how)
and now i have my value from the table.
what does it mean if my calculated value less than the one from the table? does that means that all means are equal or not?
Edit: nevermind, I found a tutorial by Google. and i figured it out. thanks for your time
