A scatterplot shows a pattern of points that is going \"downhill\" as you read left to right. The trend is fairly straight, but it is not a perfect straight line. Which of the following correlations is possible for this scatterplot?

-1

-.8

.8

1

Solution

Downhill as we read from left to right

So, this means, the correlation coefficient r must be NEGATIVE

So, this eliminates options C and D

Now, if r = -1, then it indicates that the line is EXACTLY LINEAR

But it has been given that it is not exactly linear...

So, the answer has to be :

-0.8

OPtion B
