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.
How Do You Know if a Process Is Following a Normal Distribution? Trying these tests to find out if your process is normally distributed.
Process Performance (Pp, Ppk) helps determine if your new process is acceptable by measuring ratios of distribution to spread and centering.
Cp and Cpk are considered short-term potential process capability measures for a process. We want to describe this quality in terms of sigma.
