I made a very clear point. You're just choosing to ignore it. No biggie. You can continue to live in the world of theory while the rest of us deal with reality.Not really. You presented no evidence that the averages presented were actually different rather than just an artifact of a particular sample. That is what variances (or standard deviation) can show.
So you made no point. You just presented some averages that might not be statistically different from each other that is might be the same number or maybe they actually are different, you need a measure of dispersion to know.
