Calculating P-value for one way Anova test

Hello all,

if anyone knows how to calculate p-value for one way Anova test? I know it is equal to the probability above F0 in the F α, (a-1), a(n-1) distribution. But I am not sure to find correct calculation. Any help is greatly appreciated.

Regards

Mehtap

The P value can be obtained easily by using Excel function.
If you get the F value from MSa/MSb, then the P value for the Fab is equal to FDIST(Fab,DFa, DFb). DF is degree of freedom. Hope this will help.

If you are interested in the actual formula behind it Stats: One-way ANOVA has a fairly simple explanation.
