What are the types of control charts

Control charts fall into two categories: Variable and Attribute Control Charts. Variable data are data that can be measured on a continuous scale such as a thermometer, a weighing scale, or a tape rule. Attribute data are data that are counted, for example, as good or defective, as possessing or

Therefore the use of control chart becomes very vital in Process control. There are different types of Control charts based on the data that we use. One needs to   The different types of control charts are separated into two major categories, depending on what type of process measurement you're tracking: continuous data  There are two main types of variables control charts. One (e.g. x-bar Adjusting a process which is in-control will result in increased variation. Failing to adjust a  Attribute control charts are often used to analyze these types of data in the There are two ways to track this counting type data, depending on what you are 

Control chart is a type of chart which is used to analyze how the data changes in time to time, it is also known as behavioral chart or Shewhart chart in excel, it is used in statistics in business which helps user or the viewers to analyze how any process changes, its components are control line and upper and lower control line and the means

There are two types of charts available based on sample size: c chart and u chart. C chart is used for constant sample size, and u chart is used for varying sample size. The same is illustrated in the decision tree given above. Users can choose the appropriate chart for process control. The most basic type of control chart, the individuals chart, is effective for most types of continuous data. With attribute data, however, other types of control charts are more powerful. The control limits are calculated differently to provide better detection of special causes based on the distribution of the underlying data.

There are many different subspecies of control charts which can be applied to the different types of process data which are typically available. All control charts 

However, multivariate control charts are more difficult to interpret than classic Shewhart control charts. For example, the scale on multivariate control charts is unrelated to the scale of any of the variables. Also, out-of-control signals on multivariate control charts do not reveal which variable (or combination of variables) caused the signal. Also called: Shewhart chart, statistical process control chart. The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit. Selecting the right control chart is often a challenge. The procedure below shows how to select the right chart for the right situation. The control charts included are four attributes control charts (p, np, c, and u) and three variables control charts (Xbar-R, Xbar-s, and X- mR). This chart shows the changes in the process over time. By getting an insight into the process changes, it is possible to spot problems and correct them. Project managers frequently use this chart in quality control processes. It also gives a way to control ongoing processes by searching for problems and correcting them.

The most basic type of control chart, the individuals chart, is effective for most types of continuous data. With attribute data, however, other types of control charts are more powerful. The control limits are calculated differently to provide better detection of special causes based on the distribution of the underlying data.
