Shuffling this around, I have gotten the formula: SDe = (SDb * r) - squareroot( SDc^2 + (SDb^2 * r^2) - SDb^2). Baseline The baseline mean (mean under H 0) is the number one would expect to see if all experiment participants were assigned to the control group. The mean difference is a measure of statistical dispersion equal to the average absolute difference of two independent values drawn from a probability distribution. fold change = (group1 - group2)/min (group1,group2). In other words it is the sum divided by the count. It accepts percentages directly and is versatile enough to handle negative numbers intelligently.
