The correlation between the number of hours brad studies and the grades he gets is 0.8. which phrase best describes the correlation between the number of hours brad studies and the grades he achieves?

no correlation

strong positive correlation

perfect correlation

weak positive correlation

strong negative correlation

The correct answer is "strong positive correlation". The question states that the correlation between the hours that Brad studies and the grades he gets is 0.8. This means that if Brad studies 12 hours it is very likely that he would get an 9.6 grade (12 * 0.8 = 9.6), while if he studies just 6 hours it is very likely that he would get an 4.8 grade (6 * 0.8 = 4.8). This shows that there is a strong and positive correlation, between how many hours Brad studies and how high are the grades he would get.
