OneWay ANOVA in Inference App
I am going through the User Guide to test the latest release and for my own review. I entered some data for four groups like this into the Inference app:
MAKELIST(RANDNORM(50,3),X,1,10) STO> I1 (through I3) and MAKELIST(RANDNORM(53,3),X,1,10) STO> I4 So I have generated random samples of size 10 from four populations, where the last of them is different by a mean of 3. Then I tested the null hypothesis with the oneway ANOVA. I confirmed this result in the Num view: F: 3.207 (correct) P: 0.03446 (correct) But I was surprised to see this result in the Plot view: ChiSquare: 10.8849 (?) P: 0.03446 (correct) My questions are: Why is Chi square in the plot view? Where does the Chi square statistic come form? Is the graph in the Plot view for a Chi square distribution or the F distribution? Thanks!
