If two variables are related, this would not be an appropriate application for a scatter diagram. The scatter diagram is used when you are trying to determine whether the two variables are related. 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. The better the correlation, the tighter the points will be to the correlation line.
