SB P/S #67

I understand C is incorrect due to the extreme wording of 'excellent' under a low correlation of 38%.
1. If the question were changed to +0.5 (50%) would that make C correct? or still A.
2. If the question were changed to -0.38 (negative correlation), I am assuming A would still be correct?

+0.50 correlation still isn't particularly good. Not enough to warrant "excellent." Not to mention that "g" is still speculative and may not necessarily even exist.

2. If the question were changed to -0.38 (negative correlation), I am assuming A would still be correct?

In that case, "g" may not exist at all! There could be a common factor that makes you perform well on one test but poorly on another but it's more likely that there's a zero-sum game between verbal and spatial intelligence. That is, you can only improve one at the expense of the other!

When I answered this question, I thought of "g" as the IQ, which cannot be exactly tested by tests

therefore the correlation being +0.38, or any other number, would not affect how exact the IQ is.


@aldol16 has a better explanation though
