Question

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?
o positive correlation, likely causal
o positive correlation, not likely causal
o negative correlation, likely causal
o negative correlation, not likely causal

Explanation:

A correlation coefficient \(r = 0.97\) is close to 1, indicating a strong positive linear - relationship between the minutes stayed on task in class and the grade on homework. However, just because there is a correlation does not mean one variable causes the other. There could be other factors at play.

Answer:

positive correlation, likely not causal
