Question

Identify whether the solution is correct. Identify the error, if there is one. 

1) A student at a large high school thinks that the longer a student has been at the school, the less they like the food in the dining hall. To test this theory, she gives a two question survey to the first 100 people who enter the cafeteria on a certain day. The first question is, “How long have you attended school here?" The second question asks the student to rate the food in the dining hall on a 1 to 5 scale, with 5 being the best. Comment briefly on the extent to which results can be generalized to some large population, and the extent to which cause and effect has been established. Solution? Because the students were not randomly sampled, the study cannot generalize to the entire school population. If a strong enough correlation is found between years at the school and dining hall food rating, cause and effect can be established.
