Scatterplot Graph

Scatterplot URL

Scatterplots are graphs that use dots to represent two different variables.  The vertical axis and horizontal axis both include a set of data, and each point on the graph is the combination of the two points.  Usually, these graphs are used to experiment to see if one variable is correlated to another variable.  In this graph, for example, grip strength is being compared with arm strength.  It has a general direction of a positive correlation.  This means that generally the greater the grip strength, the greater the arm strength as well.
