Five friends each conducted different studies comparing two variables. Each friend calculated the correlation coefficient, r, for their variables. Which r values suggest strong linear relationships? Select all that apply.

The strong linear relationships are:

r = 0.95

r=-0.83

Step-by-step explanation:

When we have points whit apparent linear tents, we can fit the curve to a line and when the correlation coefficient (r) is equal to 1, we have perfect correlation and when r is equal to 0 we do not have a correlation.

Therefore r =  0.95 suggest strong linear relationships.

Now, we can use the same analysis with a negative value of r, so r = -0.83 is strong too.

I hope it helps you!
