Calculating effect sizes, David Wilson

Описание к видео Calculating effect sizes, David Wilson

What we should be interested in, in terms of our policy and research, is not "statistical significance", but what did we find? How big was the effect? What direction was the effect in? This advanced workshop on effect sizes was recorded in Washington at the Campbell Colloquium 2011.
