A scatter plot is a graph that shows whether there is a
correlation, or relationship, between two sets of data. If the data
cluster around a line that is drawn from lower left to upper right,
there is a positive correlation. If the line that is drawn is from
upper left to lower right, there is a negative correlation.
If a line cannot be drawn, there is no correlation.
