The X-Bar and S Charts procedure creates control charts for a single numeric variable where the data have been collected in subgroups. It creates both an X-bar chart to monitor the subgroup means and an S chart to monitor the subgroup standard deviations.
What are X Bar S Control Charts? X Bar S charts often use control charts to examine the process mean and standard deviation over time. These charts are used when the subgroups have large sample sizes. Conversely, the S charts provide a better understanding of the spread of subgroup data than the range.
There are three types of control charts used determine if data is out of control, x-bar charts, r-charts and s-charts. An x-bar chart is often paired with either an r-chart or an s-chart to give a complete picture of the same set of data.

The X-bar and S charts are types of control charts used in statistical process control (SPC) to monitor the process mean (average) and process variability (standard deviation) over time, respectively.
14 Σεπ 2023 · But how can you decide which graph style to use? In mathematics and statistics, various forms of graphs are used to display data in a graphical format. The most popular and widely used types of charts or graphs that we will discuss in this blog.
The X-Bar and S-Squared Charts procedure creates control charts for a single numeric variable where the data have been collected in subgroups. It creates both an X-bar chart to monitor the subgroup means and an S2 chart to monitor the subgroup variances.
