The graph of the scatter plots shows that, when the value of x-coordinate that is the number of products sale is increase, then the value of y that is commission is increase
By the definition of positive correlation: if y trend is increase when X trends is increase then the two data have positive correlation Therefore, the data set of number of product sale and the value of commission earned have positive correlation.
