Definitely not 1.3 or --1.8, those are way off!

I thought it could only be between -1 and 1?

Wait, can the correlation be less than -1?

Looks like a strong negative correlation, so probably --.9.

I feel like --.9 makes sense here, but I’m worried I might be overthinking it.

I practiced a similar question where the points were also close to a line, and I think I chose a negative value then too.

I’m not entirely sure, but I think a correlation of 0 means no relationship, which doesn’t fit this scenario.

I remember that a strong negative correlation would be close to -1, so maybe --.9 could be the right answer?

Okay, let's see. I know nodes can have priority values, so that's one. Connection limits and loadbalancing mode also seem relevant.

Hmm, I'm a bit unsure about this one. I know there are a few ways to handle logging in ODI, but I can't quite remember the specific steps. I'll have to think this through carefully.

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.

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.
