__is bigger than the__**Fobt**__value__**Fcrit****THERE IS**a statistically significant difference.http://www.isixsigma.com/index.php?option=com_k2&view=item&id=1323:how-to-compare-data-sets-anova&Itemid=196&tmpl=component&print=1

**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 p-value 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

**44** Re: Statistics Psycho Exams on Wed Jun 09, 2010 5:29 am

no i was asking about the A and B factors.

thanx both of you!!
