We have substantially revised and improved the
WISE tutorial on statistical power.
The new tutorial includes improved exercises with more feedback, plus supplemental
materials on calculations and demonstrations. The earlier version is still available at
legacy power tutorial.
We appreciate your feedback and suggestions.
