Chris makes an observation that the longer a classroom lecture is, the lower the attentiveness of students in the class. In the context of correlational research, the length of the lecture and level of attentiveness are said to have a(n) .

The correct answer is Negative Correlation

Correlation is the standardized measure of the relationship between two variables.

The correlation can never be greater than 1 or less than less 1. A correlation close to zero indicates that the two variables are not related. A positive correlation indicates that the two variables move together, and the relationship is strong the closer the correlation gets to one. A negative correlation indicates that the two variables move in opposite directions, and that the relationship also becomes stronger the closer to minus 1 the correlation becomes. Two variables that are perfectly positively correlated (r = 1) move essentially in perfect proportion in the same direction, while two sets that are perfectly negatively correlated move in perfect proportion in opposite directions.
