Individual And Moving Range Chart

Individual And Moving Range Chart - Table a summarizes the focus of each chart and gives examples of measures that might be analyzed using this method. Web the individual and moving range chart is the simplest of the variable data control chart. This lesson explains how the data is recorded and interpreted on the chart. If we collect individual measurements and need to plot the data on a control chart, or assess the capability of a process, we need a way to estimate the variation over time. Moving range used to derive upper and lower limits. This chart is used to plot continuous data. Typically, an initial series of observations is used to estimate the mean and standard deviation of a process. Web use moving range chart to monitor the variation of your process when you have continuous data that are individual observations not in subgroups. Like most other variables control charts, it is actually two charts. The lesson will include practice creating the chart.
