When a scatter plot shows a positive association means that there is a linear correlation with a positive slope between the two variables. This correlation can be weaker or stronger (depending on the value of the correlation).
If there is a linear correlation between the two variables, the relation is then a direct proportionality (with slope positive or negative).
Hence, it is always true that <span>a scatter plot that shows a positive association suggests that the relationship is proportional.</span>
