how do I input a one-way anova function?

3 views (last 30 days)
I have 4 sample sizes. The first one has 11 observations, the second and fourth ones have 9 and the third one has 8. I am told that as inputs I have to include these 4 samples and the level of significance which in this case is 0.05. How do i make this function in such a way that gives me one-way anova results please?
Thank you in advance

scores = []; % list the 37 scores inside the brackets, all of group 1 first, then group 2, etc
group = {'a' 'a' 'a' } % list 37 group codes, i.e. 11 a's for group 1, then 9 'b's for group 2, etc
[p,tbl,stats] = anova1(scores,group);
The p value is part of the output and you can just check whether it is less than 0.05

Please accept my answer if it has given you the anova results you were after.
For conditioning on the test result, you can use for example
rejectH0 = p<0.05;
if rejectH0
% commands if H0 rejected
else
% commands if H0 not rejected
end

I will let you know when I try it out. Many thanks
