Study links procrastination to poorer performance on assignments

September 15, 2014

The results of a 5-year study of marketing students at the Warwick Business School show an inverse correlation between procrastination and grades. The study of 777 students found that students who turned in assignments just before a deadline performed worse on assignments than those who turned in their work more than 24 hours early. There was little statistical difference among students who submitted assignments more than 24 hours early; however, after the 24-hour mark, average scores dropped at an increasing rate the closer the submission time was to the deadline. There was a 5% difference in scores between students who submitted their work at the last minute and those who submitted it more than a day in advance, good for a full letter grade. BusinessWeek
