yeah it is almost 1 but it is not 1 so the closest possible answer is .6


If you wanna play a game, click on the link below and go the bottom of the page and move the cursor up to 1 and see the scatter plot.

r =1 means the values are highly concentrated to a straight line ..... this graph is an example of widely scattered value around a straight line .... so it is a positive line but less than 1 ......
