Chris makes an observation that the longer a classroom lecture, 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:

high negative correlation

Explanation:

Correlation means that two variables move together; regardless the direction of the response. Correlation is mesaured in values from -1 to 1, if it is close to 1, the two variables move toghether in the same direction, if it is close to -1 the two variables move toghether in oposite directions (such as the length of the lecture and the level of attentiveness). In this two cases, the variables are correlated

If it is close to 0, the variables move in different directions and the variables are not correlated
