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.
