A scatter plot is a graph made by plotting ordered pairs in a coordinate plane to show the correlation between two sets of data.
A scatter plot describes a positive trend if, as one set of values increases, the other set tends to increase.
A scatter plot describes a negative trend if, as one set of values increases, the other set tends to decrease.
A scatter plot shows no trend if the ordered pairs show no correlation.
A. Graph 2
