Consider studying whether students who sit closer to the tea

Consider studying whether students who sit closer to the teacher tend to have higher quiz scores than students who sit farther away from the teacher. Suppose you measure distance from the teacher and average quiz score for a group of students. Explain how you know if the following statement is in error:

The correlation is –0.8, so there is no association between distance and quiz average.

A correlation coefficient of –0.8 indicates a strong negative association.

A correlation coefficient of –0.8 indicates a moderate negative association.

A correlation coefficient of –0.8 indicates a weak negative association.

The statement is not in error.

A correlation coefficient of –0.8 indicates a strong positive association.

Solution

A correlation coefficient of –0.8 indicates a moderate negative association.
