The standard deviation or variance is an important measurement in a production process to analyse the quality of a process. A large variance is an indicator that there is a need to improve the production process by finding sources of variability in the output. The following data is the result of calculating the standard deviation from two tea bags filling machines. Sample Size 25 Variance Machine 1 0.04873 Machine 2 20 0.00620
