SOMEONE PLEASE HELP! MEDAL REWARDED! Which of these pairs of variables would you expect to be represented by a scatterplot with a positive correlation? A. The depth of the water in a pond and the amount of rainfall. B. The number of miles driven and the number of people on the bus. C. A person's height and the person's grade on the math test. D. The number of concert tickets purchased and the number of concert tickets still available for purchase.
its either A, or B, which one?
@trantom
A, because a positive correlation means as one goes up, so does the other. If there is more rainfall, the depth of the pond increases. Therefore A is the positive correlation. Now, for B it COULD be a positive correlation, but not necessarily. A is DEFINITELY a positive correlation.
also positive correlations mean that if one goes down, the other goes down.
awesome!
wow I have gotten four medals today !!!
