Repeated sampling of a certain process shows the average of all sample ranges to be 1.0 cm. The sample size has been constant at n = 5. What are the 3-sigma control limits for this R-chart?
Sigma Control Limits
Statistical boundaries set in process control that represent acceptable variations in product quality or process performance, typically associated with Six Sigma methodology.
Sample Ranges
The difference between the highest and lowest values in a set of data samples, often used in statistical analysis to measure variability.
- Apply analytical skills to calculate and interpret control limits and process capabilities in various control chart types such as X-bar, R-chart, p-chart, and c-chart.
- Engage the 3-sigma principles to determine control mechanisms in processes.
