Question #a74b4
1 Answer
Positive correlation
Explanation:
There are two variables in these problems, in your case it is rank and best finish.
How to determine correlation:
If one variable is going up and the other is also going up = positive
If one is going down and the other is also going down = positive
If one is going up and the other is going down = negative
Since an increased rank leads to an increased finish, the correlation is positive.
Question 16 is an example of negative correlation, because a lower row leads to a larger ticket cost.
Question 15 is slightly confusing because you are dealing with variables like rank where being ranked with the lowest number is considered the best (1st is better than 7th). Just ignore that and look at the numbers. The smaller the rank, the smaller the finish and similarly the larger the rank, the larger the finish.
