The art teacher did not survey a representative sample of students.
What is a representative sample?
This refers to a group of people that are surveyed or studied to understand the point of view or behavior of the population they represent. In this case, the sample of students represents all students in a school.
Is this sample representative?
A sample is representative if it effectively represents the general opinion or behavior of a population. To guarantee this, the researcher must select people with a variety of traits. In this case, this would include:
- Students who are in the art class.
- Students who are not in the art class.
As the teacher mainly surveyed students who are already enrolled, the sample is not representative as this can modify the results of the survey.
