Answers

Answer 1

Answer:

A researcher has found that students who sleep more in class get lower grades on their exams. This is an example of a negative correlation. Therefore, the correct option is option C.

A negative correlation indicates that as one variable rises, the other falls. In this situation, the researcher discovered that as the amount of sleep in class increases, so do exam grades. This suggests that there is a negative relationship between the amount of sleep in class and exam grades.

A positive correlation (A) would indicate that as one variable increases, the other variable also increases. An independent variable (B) refers to the variable that is manipulated or controlled by the researcher. A dependent variable (D) refers to the variable that is measured or observed to determine the effects of the independent variable.

Therefore, the correct option is option C.
