Amazingly, the standard deviation of each sample was the same at .63 seconds. Power Analysis: I. Using Cohen's D formula (shown below) for determining effect size, we see that our current study with sample means of 1.004 and .589 respectively for the control and treatment groups and equal standard deviation of .63 generates an effect size of .66.
