Evaluating Study Time Impact on Math Scores

In a recent study, researchers found that students who study at night score higher on math tests compared to those who study in the morning. Based on this study, the school's principal concluded that if students want to improve their math scores, they should change their study habits to focus on studying at night.

This reasoning assumes that there are no other significant factors affecting the math scores of the students, such as the quality of study materials or the individual learning styles of students.
