Continuous Metric Control Charts: the X-Bar & R-chart

This video discusses the Continuous Metric Control Charts. Continuous Metric control charts are "measured" to detect the shift of the mean or dispersion. The charts we will cover are x-bar charts (detect the shift of the mean) and R-charts (detect the shift of dispersion). We will learn how to use the Control Chart Factors table and identify the Sample Size (A2) the Upper Range (D4) and Lower Range (D3). We will discuss the how to create these control charts, explain the equations for both, and walk through examples how to calculate them.
