Scatterplot

http://blogs.mygns.ca/groups/math8v/weblog/d22e6/

Scatterplots are used to plot either one individual or multiple indivuals observations into a diagram so that a trend may be determined between the subjects. For instance, this graph is comparing how years of experience relate to income. The solid line in the middle is the trend line which shows either a negative or positive correlation between these two subjects; for this map there is a possitive correlation.
