Quality Control Chart
Different types of quality control charts, such as X-bar charts, S charts and Np charts are used depending on the type of data that needs to be analyzed. A quality control chart can also be univariate or multivariate, meaning that it can show whether a product or process deviates from one or from more than one desired result.
