SCATTER DIAGRAM

The scatter diagram is a technique used to examine the relationship between both the axis (X and Y) with one variable. In the graph, if the variables are correlated, the point will drop along a curve or line. A scatter diagram or scatter plot, is used to give an idea idea of the nature of relationship.  

In scatter correlation diagram, if all the points stretches in one line, then the correlation is perfect and is in unity. But,if the scatter points are widely scattered throughout the line, the correlation is said to be low. And if the scatter points rest near a line or on a line the correlation is said to be linear.
