Control charts are an essential Instrument during the Six Sigma methodology to monitor and control approach variation. Six Sigma is a data-driven method of method enhancement that aims to minimize defects and boost good quality by figuring out and reducing the sources of variation in more info a system.
The X Bar S Chart is comparable to your X Bar R Chart but uses the sample standard deviation rather than the variety. It truly is appropriate for continual details types. It's employed when the procedure facts is Commonly distributed, and the sample measurement is multiple.
