Question
Suppose there is a strong positive correlation between a and b. Which of the following must be true?A.An increase in a causes b to increase.B.When a increases, b tends to decrease.C.When a increases, b tends to increase.D.An increase in a causes b to decrease.SUBMITarrow_backPREVIOUS
Solution
The correct answer is C. When a increases, b tends to increase. This is because a strong positive correlation means that as one variable increases, the other also tends to increase. It's important to note that correlation does not imply causation, so we can't say that an increase in a causes b to increase (option A). Options B and D are incorrect because they suggest a negative correlation, which is the opposite of what's stated in the question.
