hey guys, me and arman want to clarify something. when the f obtain is bigger than f critical then there is a signifance right?

If Fobt is bigger than the Fcrit value THERE IS a statistically significant difference.

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??

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.

so for the p value it's the opposite. really thanks!!

what is A and what is B???
the μs??
41 null and alt on Wed Jun 09, 2010 5:13 am
doc_psy
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.

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
