Wait, are we sure about A? That doesn't seem right to me.

C seems off, isn't r2 always the square of r?

I think B is correct, they are related but not equal.

A is definitely true, r2 is always less than r.

I feel like option D is definitely wrong, but I can't quite remember how the correlation coefficient is calculated in relation to r².

I practiced a question where the Coefficient of Determination was discussed, but I can't recall if it was less than r² or not.

I think the correlation coefficient is actually the square root of r², so maybe option B could be correct?

I remember something about the r² value being related to the correlation coefficient, but I'm not sure if it's always smaller.

This is a good test of my statistical knowledge. I'll need to carefully consider the definitions of each term to determine the most likely outcome. Time to put my problem-solving skills to work!

Ah, I see what they're getting at. The r-squared value is always less than or equal to the absolute value of r, so A must be the right answer. Regression analysis is all about understanding those relationships.

I'm a little unsure about this one. The wording is a bit tricky, and I don't want to overthink it. Let me re-read the options and see if I can eliminate any of the choices.

Okay, I've got this. The r-squared value is the coefficient of determination, which is the square of the correlation coefficient r. So the correct answer must be C.

Value-add flow, production map, value stream... Ugh, I'm drawing a blank on the exact terminology here. I'll have to make an educated guess and hope for the best.

I'm going with C. It just makes the most statistical sense to me. Though I do wonder what a Regression Analysis on a Belt would actually entail...

I'm torn between A and C. The r^2 value is the square of the Correlation Coefficient, so it would be larger than the absolute value of r.
