Frequency plots help monitor the spread of continuous data. A frequency plot is a graph showing a variable’s distributional information.
Basic six sigma statistics is the foundation for six sigma projects. Numerically describe the data that characterizes process Xs & Ys.
Measurement Systems Analysis allows us to ensure that the variation in our measurement is minimal compared to the variation in our process.
Cp and Cpk are considered short-term potential process capability measures for a process. We want to describe this quality in terms of sigma.
Preventive techniques in six sigma are used to proactively identify and address potential problems or defects before they occur.
