240 students responded to the imaginary student canteen survey. The survey asked whether the student chose a meat or vegetable dish for lunch. In addition, we asked for an opinion on the quality of the food on a scale of 1-5, where 1 means the worst and 5 the best. 131 of the students chose vegetarian food and 109 meat food. Of those who chose vegetarian food, 17 students gave a grade 1, 25 students gave a grade 2, 38 students gave a grade 3, 35 students gave a grade 4, and 16 students gave a grade 5. Of those who chose the meat dish, 14 students gave a grade 1, 29 students gave a grade 2, 42 students gave a grade 3, 20 students gave a grade 4, and 4 students gave a grade 5.
