Question

A dance student wants to know the favorite type of dance class for students at The Dance Academy. She surveys each student in her ballet class. In which way could the results of her survey be most improved?
She could sample an equal number of students in each type of dance class.
She could sample a proportional number of students in each type of dance class.
She could sample one student in each type of dance class.
She could sample one teacher from each type of dance class.

Answer 1

To improve the results of her survey, the dance student should **sample a proportional number of students in each type of dance class**. This approach ensures that the survey results reflect the preferences of the entire student body at The Dance Academy more accurately by accounting for the actual distribution of students across different dance classes. An equal number of students from each class may not represent the overall population well if some classes have significantly more students than others. Sampling one student from each class or one teacher from each class would not provide a comprehensive understanding of the students' preferences.
