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

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

Step-by-step explanation:

Causation describes a relationship between two quantities where one quantity is effected by the other.

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

Since 0.8 is near to 1, hence it shows a strong correlation.

But correlation does not imply causation because if just two quantities correlate does not necessarily means that one causes the other.

Hence, the given conclusion is not reasonable .
