| Nov 1, 2015 at 11:30 | comment | added | flaminka | Just comparing these values, nothing formal ( maybe that's the case ) - I think that when second variance is almost three times greater than first one and one and a half greater than the third one, then I can't assume that they are equal :) | |
| Nov 1, 2015 at 10:50 | comment | added | Glen_b | On what basis do you assert significance when you say: "see that the second one is significantly different from the others"? | |
