Description: This paper compares the so-called exact approach for obtaining confidence intervals on normal distribution coefficients of variation to approximate methods. Approximate approaches were found to perform less well than the exact approach for large coefficients of variation and small sample sizes. Web-based computer programs are described for calculating confidence intervals on coefficients of variation for normally and lognormally distributed data.
Keywords: Noncentral T, noise to signal ratio, variability, coefficient of variation, confidence bounds, normal, lognormal
