Method 2 is the least biased.

1) vegetarians are a select group, so they might have a certain biased perspective

2) if students are chosen randomly from every grade, all grades are included and there will be a variety of responses

3) not all students dislike the program, so it is an unfair representation

4) only students who have a strong opinion will complete the survey
