Control charts are specifically designed to identify and differentiate between common cause variation and special cause variation. They help to show when a process is operating within its normal limits (common cause variation) or when there are specific factors affecting the process (special cause variation). Pareto charts, run charts, and scatter diagrams are useful tools in quality improvement and data analysis, but they do not specifically address the differentiation between common cause variation and special cause variation.
