Abstract: Confidence regions for the standard deviation of a normally distributed variate based on the mean range of a number of samples. The mean range of a number of small samples from normal populations with the same standard deviation a is often used to derive point‐ and interval estimates of this parameter. This paper provides tables which facilitate the computation of interval estimates and considers the problem, how many samples of size 5 or 7 must be used in order to attain a given accuracy in the estimation.
