11 Interpretation The prospect theory generally doesn’t hold true Students who hold executive positions are more inclined to follow the theory Students who join extracurricular activities are more inclined to follow the theory except for athletes and Sociocivic As students fail more, they tend to disagree with the prospect theory Those with high CGPA tend to disagree with the prospect theory Male are more inclined to follow the theory Those who are single are more inclined to follow the theory As years goes by, students tend to disagree with the prospect theory
