Question

The correlation coefficient for practicing violin and getting better grades in a group of people is 0.8. Analyze the following statement.

Playing violin causes students to get better grades.

Is this a reasonable conclusion?

Yes; students who play violin must necessarily get better grades

Yes; the correlation coefficient is above 0.5, so that implies causation

No; playing violin and earning better grades are completely unrelated

No; even though there is a strong positive correlation, playing violin doesn't cause students to get better grades

Answer 5

No, it is not a reasonable conclusion. Playing the violin doesn't cause you to get better grades, nor does getting better grades cause you to take up the violin (or play it better).

However, skills that help you play the violin (attention to detail, willingness to work, etc.) are also skills which may help you get better grades. So, correlation, but not causality.

Answer 6

its c

Answer 7

^hes wrong

Answer 8

Yeah, sure I am.

Answer 9

thank you for agreeing

Answer 10

0.8 positive correlation coefficient is a strong one.

Answer 11

But do enlighten us — what is incorrect about my answer?

Answer 12

What specifically makes C a superior answer? I think we agree that A and B are out.

Answer 13

ok if you actually look at this in a different way causation is " one thing happenes because of another" so if you look at its asking causation not correlation so when you read the problem playing the violin does not have to do with anything about getting grades. Its not asking if it correleates its asking you if one thing couses the other

Answer 14

its asking a causation and they both have nothing to do with each other

Answer 15

Which part of answer D is incorrect, hmm?

Answer 16

you dont know if theres any other information besides .8

Answer 17

you cant rely on .8 to be a correlation you need a line instead of one point

Answer 18

i think it coud be d because it is a strong posative corralation but does not mean it causes a better grde

Answer 19

What do you think "The correlation coefficient [...] is 0.8" means? It's not referring to a point, it is referring to a relationship between two variables.

Answer 20

D was correct

Answer 21

my mistake im sorry

Answer 22

can i still have credit for argueing

Answer 23

or debating\

Answer 24

From practical experience as a violinist and student for many years, I can attest that what I said is true, at least in my experience: the skills necessary to become a good violinist tend to give you the tools to be a good student. It isn't causation, because you won't necessarily apply them, and some people are naturally gifted and don't have to "study", but there is a large positive correlation.

Answer 25

There's no button for "give credit for debating" but I'll give you a medal for admitting your mistake, which is a classy move in my book.

Answer 26

The correct answer is D. ''No; even though there is a strong positive correlation, playing violin doesn't cause students to get better grades'' TOOK the test & got it Right.

Answer 27

Pretty sure OP just said that

Answer 28

lol
