It is sometimes necessary to transform data to, for example, downweight the influence of outliers, prior to performing any analysis. The reciprocal of reaction times is used for this purpose.
A transformed mean, m, with variance s2 on a sample of size, n, has a backtransformed variance (ie on the original scale) given below.
