**Table 1:** Statistical Results of paired two tailed T-tests comparing group performance at time 1 and at the last performance. The alpha value was set at p < 0.01, the threshold probability for rejecting the null hypothesis, an indication of type I error rate. The β threshold was set at 0.200 Probability of failing to reject the null hypothesis under the alternative hypothesis, an indication of type II error rate. The mean is the difference between pre and post-performance. The standard deviations is based upon the underlying outcome measurement, assumed to be the same at both time points, and within-subject correlation of the outcome. See: http://www.sample-size.net/effect-size-study-paired-t-test/. The effects sizes are all well beyond 2.0 indicating there was less than 3% overlap between the scores at the first time measured and the second. The effect seizes here demonstrate the potent interventions utilizes that produced such big have bigger effect sizes in a small sample [9].
