Types Of Control Charts
What is types of control charts?
Control charts are statistical tools used to monitor and control processes. They provide a visual representation of data over time, allowing users to identify any patterns or trends that may be occurring in the process. There are several types of control charts that can be used, depending on the type of data being collected and the objective of the analysis. These include:
What are the types of types of control charts?
1. X-Bar and R charts: These charts are used when the data collected is continuous and the subgroups consist of multiple observations. X-Bar charts monitor the mean value of the process, while R charts monitor the range or variability of the process.
Individuals charts: These charts are used when the data collected is continuous and the subgroups consist of a single observation. Individuals charts monitor the individual values of the process and are useful for detecting small shifts or outliers.
Attribute charts: These charts are used when the data collected is categorical or binary. They are used to monitor the proportion of nonconforming units or the number of nonconformities in a sample.
Moving range charts: These charts are used when the data collected is continuous and the subgroups consist of multiple observations. Moving range charts monitor the variation within each subgroup and are used to detect shifts in the process variability.
How to complete types of control charts
To complete a control chart, follow these steps:
01
Collect the data: Determine the type of data you need to collect and gather the necessary information.
02
Select the appropriate type of control chart: Choose the control chart that is most suitable for your data and analysis objective.
03
Calculate the control limits: Determine the control limits for the selected control chart based on the collected data.
04
Plot the data: Graphically represent the data on the control chart, with the x-axis representing time and the y-axis representing the measured values.
05
Analyze the data: Monitor the plotted data over time and look for any patterns, trends, or points that fall outside the control limits.
06
Take corrective actions: If any issues or abnormalities are detected, take appropriate actions to address and control the process.

Individuals and Moving Range Chart The individuals and moving range (I-MR) chart is one of the most commonly used control charts for continuous data. it is applicable when one data point is collected at each point in time.
What are the 4 types of control charts?
Types of Control Charts X-Chart. X-Charts present variable data. P-Chart. P-Charts are used for data that is counted. NP-Chart. NP-Charts are used to present the number of nonconforming or conforming items. C-Chart. U-Chart. MR-Chart. Individual MR-Chart. Custom Data Control Chart.
What are control charts and its types?
There are three types of control charts: (1) C-chart that measures the number of nonconformities (such as defects or errors) over time, (2) R-chart which shows the range of each sample set or subgroup over time, and (3) S-chart which shows the standard deviation of each sample set or subgroup over time.
