hey guys, me and arman want to clarify something. when the f obtain is bigger than f critical then there is a signifance right?
34 Explaning the Fs on Wed Jun 09, 2010 12:58 am
If Fobt is bigger than the Fcrit value THERE IS a statistically significant difference.

35 Re: Statistics Psycho Exams on Wed Jun 09, 2010 1:01 am
so hypothesis is confirmed? and null hypothesis rejected?? and all these only if Fobt is bigger than Fcrit?? and what if he doesn't give us the Fcrit??
36 Re: Statistics Psycho Exams on Wed Jun 09, 2010 1:19 am
So we reject a null hypothesis and accept the alternate if F obtain is > than F critical .The F is always given in a one or two way ANOVA but if there is no F you can see it from the pvalue that it is significant at 0,05 . This means if its lower than 0,05 it is significant.
37 Re: Statistics Psycho Exams on Wed Jun 09, 2010 1:22 am
so for the p value it's the opposite. really thanks!!

a) state the null and alternate hypotheses
b) Does A play a significant role on B? Explain why?
what is A and what is B???
the μs??
41 null and alt on Wed Jun 09, 2010 5:13 am
the null states that all μs are equal and alternative staes that thei are different. so we use post hoc do find WHICH μs differ.
42 Re: Statistics Psycho Exams on Wed Jun 09, 2010 5:25 am
Teo, actually the A and B factors are the variables...let's say that you have volume and gender inside the table..it's like A and B
