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.

14.What correlation, if any, do you see

between temperature and time?
