bretts teacher observed bretts behavior in class for a week and compared the minutes he stayed on task in class to the grade he earned on the homework that night. she found that the correlation coefficient was r = 0.97. what type of relationship has his teacher discovered? positive correlation, likely causal positive correlation, not likely causal negative correlation, likely causal negative correlation, not likely causal

Answer

Explanation:

Step1: Analyze the sign of correlation coefficient

The correlation coefficient $r = 0.97$ is positive. A positive $r$ - value indicates a positive correlation, meaning as the minutes on - task increase, the homework grade also tends to increase.

Step2: Consider causality

It is likely that the more time Brett stays on - task in class, the better understanding he has of the material, which in turn leads to a higher grade on his homework. So it is likely a causal relationship.

Answer:

positive correlation, likely causal
