WebJan 22, 2024 · The ASTM E178-16a standard for detecting outliers from a univariate normal distribution includes the skewness outlier test. The test statistic is the adjusted Fisher-Pearson skewness coefficient. with n, and s denoting the sample size, the sample mean and the sample standard deviation, respectively. The critical values are obtained via simulation. WebSample Skewness - Formula and Calculation. If your data hold a simple random sample from some population, use.
