What is Statistical Quality Control?

Statistical Quality Control is a method used in measuring and evaluating the quality of the product. There are three categories in statistical quality control, and each of these categories is effectively used in product quality evaluation. These categories are Descriptive Statistics, Statistical Process Control, and Acceptance Sampling. Each of these categories employs statistical tools which are used in analyzing the quality of the products. While all of these categories are helpful in quality analysis, the most frequently used is the Statistical Process Control practically because quality control is integrated into every process resulting into the identification of quality problems in the production process.
