Recognizing the potential importance of new uses of analysis, the author provides an alternative approach for constructing the confidence interval (C.I.) for the population coefficient of variation, V =α/μ. More specifically, the comment demonstrates the use of some of the existing percentage points of the sample coefficient of variation, v = s/ x . The results of these approximations are then compared empirically with the results recently published by Hayya, Copeland and Chan [1, pp. 115–118]. The available approximations given by Iglewicz [2] and again by Iglewicz and Myers [3] of the practical range of V and of the sample size n are more accurate than those obtained using the method in [1].
