Although it does not provide information regarding the individual values in the dataset, it delivers a comprehensive summary of the whole dataset. View Answer Answer: p-chart 30 Dispersion of a process in monitored in A Range chart. It provides a way of assigning an average value to a set of numerical quantities. Control charts and run charts provide good illustrations of process stability or instability. R chart values or s chart values indicate that … If there are two or more most frequently occurring values in the supplied data, the function returns the lowest are located on the same spot on the graph. 10 C. 8 D. .12 E. 0.8 Quantitative analysis is the process of collecting and evaluating measurable and verifiable data such as revenues, market share, and wages in order to understand the behavior and performance of a business.
