Page 1 1 Scatter Diagram Page 2 1 Scatter Diagram 2 What is Scatter Diagram? The scatter diagram graphs pairs of numerical data, with one variable on each axis, to look for a relationship between them. If the variables are correlated, the points will fall along a line or curve. Page 3 1 Scatter Diagram 2 What is Scatter Diagram? The scatter diagram graphs pairs of numerical data, with one variable on each axis, to look for a relationship between them. If the variables are correlated, the points will fall along a line or curve. 3 â€¢ The scatter diagram is used to find the correlation between two variables. â€¢ This diagram shows you how closely the two variables are related. â€¢ After determining the correlation between the variables, you can easily predict the behavior of the other variable. â€¢ This chart is very useful when one variable is easy to measure and the other is not.

It only shows the quantitative expression of the quantitative change. â€¢ This chart does not show you the relationship for more than two variables.Read More
