I circled the one that I think is the answer and pointed to the one which MAV thinks is correct. Who's right?
Question 11 shows that there is a trend there that appears to have a moderate correlation. There is likely some sort of explanation, making C more correct.
Question 6 is B. Sorry man. An r value (correlation coefficient) of 0.68 is positive and of
moderate strength, not weak. This is one of those where you have to watch the wording to get right.
A little explanation...
Options A and D are incorrect because it's not a coefficient of determination. C is wrong because it's not "causal", it's an association/ correlation. Math doesn't work quite the way E says it to be.
Hi, would really appreciate if someone could help with this question. I don't understand why it's C and not B. Thanks!
Spoiler
There's a bit of a trick to this question because it's not actually clear, but the difference is in the slope. Yeah, that's the tricky part. If you go back and graph the two graphs into the calculator, you'd realise there's a solid gap between x = 0 and x = 0.3 for Option B, which doesn't appear in this graph. Measuring this graph, you can see that the gap is really small, like smaller than 0.3. Luckily, VCAA are usually clearer than this.
I just realised I was beaten to the punch. Oh well, hopefully these help somebody.
