Scatter Diagrams
A Scatter Diagram examines the relationships between data collected for two different characteristics. Although the Scatter Diagram cannot determine the cause of such a relationship, it can show whether or not such a relationship exists, and if so, just how strong it is. The analysis produced by the Scatter Diagram is called Regression Analysis.
