18 Dec 2013 with the door-closing mechanism. There are many types of control chart. For example, the widely used statistical software package Minitab This research introduced how to design and implement short-run control chart for Other types of difference control charts are compared with the δ chart and the To develop the control charts for this research, we used the Minitab software. Minitab offers four multivariate control charts: A chart of that uses a special statistic (Hotelling's T2) combining dispersion and mean information from several Plotted points that are higher on a control chart for rare events indicate a longer time between events. Plotted points that are lower on the chart indicate less time between events. Some events occur so infrequently that you cannot use a traditional control chart, such as an Xbar-R or P chart, to monitor your data.
Other control charts are ideal for other types of data. For example, the U Chart and Laney U’ Chart use the Poisson distribution. The P Chart and Laney P’ Chart use the binomial distribution.

Plotted points that are lower on the chart indicate less time between events. Some events occur so infrequently that you cannot use a traditional control chart, such as an Xbar-R or P chart, to monitor your data. Minitab also offers two other types of variables charts for more complex applications: Time-weighted control charts – Use historical data points to help you track small shifts in a process. Multivariate control charts – Show how correlated variables jointly affect a process or outcome. In an earlier post, I wrote about the common elements that all control charts share: upper and lower control limits, an expected variation region, and an unexpected (or special cause) variation region.
