Question

Accepted Answer

Control charts are statistical tools used to monitor processes and detect any changes or variations in data.

Control charts help in identifying if a process is stable or if there are any special causes of variation present.
Variable control charts are used when the data being measured is continuous, such as weight or length.
Attribute control charts are used when the data being measured is discrete and can be counted, such as the number of defects in a product.
Control charts typically consist of a central line representing the mean, upper and lower control limits, and data points plotted over time.
Examples of control charts include X-bar and R charts for variable data, and p and c charts for attribute data.
