Answer:
Scatter Diagrams are convenient mathematical tools to study the correlation between two random variables. As the name suggests, they are a form of a sheet of paper upon which the data points corresponding to the variables of interest, are scattered. Judging by the shape of the pattern that the data points form on this sheet of paper, we can determine the association between the two variables, and can further apply the best suitable correlation analysis technique.
