Students who watch more television perform more poorly on their exams.

Explanation:

Television can be very detrimental to students' academic performance. There needs to be a balance between the amount of time a student is watching and the amount of time he is studying, doing physical and academic activities, and sleeping.

The more time the student spends assuming the less time he will have for other activities. With this, the activities of academic nature will be impaired, the student will not give enough attention to the studies and with that the academic performance of this student will fall.
