Question: Is the F-test significant at the 5 percent significance level?
Answer: Yes. The significance of 0.00904 given in the table is the p-value of the test. This is less than the specified significance level of 0.05, so we reject the null hypothesis.
WILL THE P-VALUE ALWAYS BE GIVEN TO US? I HAVE NO IDEA WHERE TO GET THE P-VALUE ON THE EXAM!?! HELP!?!作者: tianxin 时间: 2011-7-13 13:37
p-values are usually output in the ANOVA table. If they require you to use it, they will provide it.

Even if P value is given, look at the F stat of 37. That is really high, considering you have 2 independent variables.

Usually, if the F stat value is too large, as in your example, p-value is usually small enough to reject the null.作者: ppls 时间: 2011-7-13 13:37
p-value is the smallest level of significance (1-alpha) at which we can reject the null. so if p < the level of sig, F-test (or whatever test) indicates significance.作者: madaochenggong 时间: 2011-7-13 13:37
That is a output from the ANOVA. There is no way p-value can be calculated by you...
We cannot calculate it, at least not with what we have learnt in the curriculum.
you can make an indication of what the max p-value may be - which is the 1-Level of significance... nothing more than that.

right. you can get a range by looking at the table. they may not give it to you. you might have to look it up in table.
