Support for the way of managing charts.
We will provide support for the management chart's structure.
There are two types of control charts: 1. Measurement values and 2. Count values. 1. Control charts for measurement values Control charts for measurement values use continuously changing data. Typical examples include the "X-R control chart" and the "X-s control chart." In the X-R control chart, the average value X within a group is graphed in the X chart, and the range R within each group is graphed in the R chart. These are arranged vertically to allow simultaneous viewing of the data's average and distribution range, resulting in the X-R control chart. The X-s control chart creates an X-R control chart that graphs the average value within a group and an s chart that graphs the standard deviation of the data for each group. These are also arranged vertically to allow simultaneous viewing of the average value and standard deviation. The X-R control chart, which uses the maximum and minimum values of the data, can lead to a large number of data points, making it difficult to see the variation within the range. The X-s control chart uses the standard deviation s instead of the range R to make the variation clearer. 2. Control charts for count values Control charts for count values use discrete data. The main types include "P control chart," "Pn control chart," "C control chart," and "U control chart." Based on the above, we will provide support regarding the appropriate use of control charts.
