# F value in ANOVA table?

Topic: Rejecting null hypothesis of anova tests
June 16, 2019 / By Donough
Question: I have an ANOVA table where I have F value = 0.00 and P<0.0001. How do I interpret these results? what does F value tell me in this case? Thanks note: DF=1

This is not a question asking for helpso that you can complete possibly homework, or a project at school/college. It is an instruction to do something for you without even a please!

You seem to be missing some details from your ANOVA table, but your values are telling of another problem. 1. The F value is calculated generally by dividing MS source / MS error or this can be thought of as the variance due to effect / variance due to error. An F that is equal to 1 would suggest that both the variance from effect and the variance from the error are equal or the same... This is very common and is usually associate with a very high probability that your result is due to chance... but in your case the F value is less than 1 suggesting that the variance due to error is higher than the variance due to source. Since the F probability distribution has two tails it is also very unlikely to have very low F values due to chance. This is why you have such a low P value... the problem is this F value makes your result uninterpretable because as I mentioned you have the opposite of an effect... you may have some other issue with your data set.

OK. Your F value is so less which is good. Your F value has p<0.0001 which indicate that your null hypothesis can not be rejected. In other words the probability of being wrong of your decision (on accepting null hypothesis )is less than 0.0001. The 1-0.0001=0.9999 is the probability of your decision be reliable.

REGION cannot be scale. You have to change it to Nominal. (Correction) I just realize the fatality rate has already been provided. You only need Table 1083: Traffic Fatalities by State. Your homework is still to assign which REGION a state should belong to. You have a total of 51 cases. You should run exploratory analysis to see if your three groups (regions) have normal distributions. However, since your smallest case still have a sample size of 43, I would simply assume it is ok to run ANOVA.
