What is the difference between control charts for variables and control charts for attributes?
Hi Osamah, usually when your measured variable is based on counting defects we use attributes control charts such as p-chart, c-chart, u-chart, ... but when your measured variable is quantitative we use continues control charts such as xbar-R, xbar-s, ...
Control charts are process behaviour charts that help us understand if the process/activity is in state of statistical control. Depending on the type of measurement various charts are available. If the measurement type is qualitative, then attributes chart is used and when quantitative variables chart is used.
This should be of help:
