Playing violin causes students to get better grades.

Is this a reasonable conclusion? ()

Answer 1

Answer:

Playing violin causes students to get better grades.  

is a reasonable conclusion

Step-by-step explanation:

Given that the correlation coefficient for practicing violin and getting better grades in a group of people is 0.8.

If practicing violin time is taken as x and getting better grades is taken as y then we are given that x and y are positive strong correlated.  Strong because correlation coefficient is >0.5

Hence the given conclusion is reasonable.

Playing violin causes students to get better grades.  

Answer 2

I think the correct answer from the choices listed above is the second option. The conclusion saying playing violin causes students to get better grades is a reasonable conclusion. This is because the correlation coefficient is above 0.5, so that implies causation. Hope this answers the question.
