I'm feeling a bit correlated out after studying all these scatter plots. Maybe I should just roll a dice and hope for the best.

Hmm, I wonder if the exam writers are trying to trick us with those crazy negative signs. But I'll stick with my gut and choose C - -0.9.

This is a classic case of a negative linear correlation. The correct answer must be C - -0.9. Time to ace this exam!

A coefficient of correlation can't be greater than 1, so options E and F are out. I'm leaning towards C - -0.9, since the line is tipping down on the right.

So, we can eliminate E and F, leaving us with A) 0.8, B) 0, C) -0.9, and D) 1 to choose from.

Yeah, a coefficient of correlation can't be greater than 1, so options E and F are definitely out.

Hmm, the scatter plot shows a strong linear relationship, so I'm thinking the coefficient of correlation should be a high positive value. I'll go with option D - 1.
