Abstract
In a recent issue of this journal, Edward E. Cureton [1] published a table of correction factors, k, which allow unbiased estimation of the standard deviation of a normal population using the sample standard deviation. Excerpts from the following table which I have recently calculated will appear in [2]. The table was calculated using double precision arithmetic and the table of logarithms of the gamma function given in [3]. The table is in a form preferred by many statisticians and is more complete than Cureton's. If n is the sample size, x2 = (X X)2, and you are given lx2 S n n-I (1)
