The esteemed Dr Bookworm has just completed a study in which he found a +1.0 correction between the number of cups of coffee his students drank right before class and the scores they earned on his final exam. This correlation means that:

A. the less coffee the students drank, the higher they scored on the exam.
B. the more coffee the students drank, the lower they scored on the exam.
C. the more coffee the students drank, the higher they scored on the exam.
D. there was absolutely no correlational relationship between coffee consumption and exam scores.

I choose D is that correct

Answer 1

D is that correct

Answer 2

No, your response of choosing option D is not correct. The correct answer is option C: the more coffee the students drank, the higher they scored on the exam. This is because the given statement mentions a positive correlation of +1.0 between the number of cups of coffee students drank and their scores on the final exam. A positive correlation indicates that as one variable (in this case, coffee consumption) increases, the other variable (exam scores) also increases. Therefore, it suggests that the more coffee the students drank, the higher they scored on the exam.
