For a school newspaper article, Cienna conducted a survey to find out students’ favorite subjects. She polled all the students in Mrs. Lopez’s advanced dance class. Why is her data likely to be skewed?

Advanced dance students are more likely to enjoy dance than students in the general population, so dance will be underrepresented.
