What is sample standard deviation? In cases where values fall outside the calculated range, it may be necessary to make changes to the production process to ensure quality control. Sp = √ ( ( s12 + s22 ) ⁄ 2) where cd is cohen's d. Add all data values and divide by the sample size n. The coefficient of variation is the ratio between the inverse of the mean and the standard deviation: But here we explain the formulas. Sp is the pooled standard deviation.
