What does it mean to say that the linear correlation coefficient between two var

Question

What does it mean to say that the linear correlation coefficient between two variables equals 1? What would the scatter diagram look like? Choose the correct answer below 0 A When the linear correlation coefficient is 1, there is a perfect negative linear relation between the two variables The scatter diagram would contain points that all lie on a line with a negative slope. O B. When the linear correlation coefficient is 1, there is a perfect horizontal linear relation between the two variables. The scatter diagram would contain points that all lie on a horizontal line. O c when the linear correlation coefficient is 1 there is a perfect positive linear relation between the two variables. The scatter diagram would contain points that all lie on a line with a positive slope O D. When the linear correlation coefficient is 1, there is no linear relation between the variables. The scatter diagram would contain points that show no discernable relationship.

Explanation / Answer

C. When the linear correlation coefficient is 1, there is perfect positive linear relation between two variables. The scatter diagram would contain points that all lie on line with positive slope.
