Control Chart

Control Chart shows the upper and lower statistical control limits, as well as the average, for samples or subgroups of a given process.In the event that all points on the control chart are within the control limits, variations can be attributed to a single cause and the process is considered to be “in control.” The fact that a point is outside of a range indicates special causes of variation, and the process is referred to as “out of control.”

Historical data is used to determine these lines. Based on the comparison of current data with these lines, you can conclude whether the variation is predictable (out of control, resulting from special causes of variation) or consistent (in control). In addition to being a versatile tool for data collection and analysis, this is also considered one of the seven basic quality tools.Control charts always have a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit. Historical data determines these lines.
Control Chart

The control charts are drawn from both fixed and variable data. Data from the process are displayed using the top chart to determine the average, or the center of the distribution. The bottom chart indicates the range, or the direction of the distribution. Based on your data, the average would represent where the shots cluster, and the range would reflect how tightly they cluster. Control charts for attribute data are used individually.
