A lecturer wants to learn if there is a relationship between the amount of time (in minutes) a student studies for an exam and the student’s mark of the exam. He finds the Pearson’s correlation coefficient between the amount of time spent for exam and the student’s mark of the exam as 0.905.
Which of the following can be inferred from the data above?
|

|
There is no linear relationship between the variables. |
|
The relationship between the variables is very weak. |
|

|
The relationship between the variables is negative. |
The Pearson’s correlation coefficient between the amount of time spent for exam and the student’s mark of the exam is 0.905. It is a positive linear relationship and it's very close to 1. Therefore, we can say there is strong positive relationship between the two variables. The correct answer is D.
