Scatter Plot

There are many problems that require a

combined analysis of two variables.

Possible questions:

Are these two variables related?

How are these variables related?

To answer such questions we plot these ordered pairs

of bivariate data on a coordinate axis system.The independent variable are plotted on the

horizontal axis and dependent variable are plotted

on the vertical axis.18(c) MSF
