Todd's method of sampling is incorrect because he chose the student from a single club. To make it better he has to choose students from different clubs.
What is a sample method?
The sampling method is the method of selecting the subset from the set to make a statical inference.
Todd surveyed the 25, 7th-grade students in the art club to determine what movies 7th-grade students prefer.
This method is not an appropriate sample to use infer preference of all 7th-grade students because they only get the students in one club, a better sampling method would get the correct surveyed from 25 grade 7 students in other clubs including the art club.
