Playing with Power: An educational simulation illustrating the relationship between means, standard deviations, alpha, and power of distributions in statistical power analysis!

This is a simple real-time simulation of apriori power analysis to examine the differences between two independent means. Although this is one specific case, the relationships between the parameters stays the same for other types of comparisons in power analysis and it is always helpful to understand mean, standard deviation, effect size, alpha, and power.
