To learn the most popular music genre among all 7th graders in a school, a teacher surveys all students in her music class. Is this sample biased or likely representative?

Likely representative — the music class includes students with various preferences.

Biased — only students enrolled in the music class are included, which over-represents students who already like music.

Biased — the sample is too small to be useful.

Likely representative — the teacher has good judgment about which students to include.
