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?

Answer 1

A) She could sample an equal number of students in each type of dance class.

B) She could sample a proportional number of students in each type of dance class.

C) She could sample one student in each type of dance class.

D) She could sample one teacher from each type of dance class.

Answer 2

Since you have not presented any choices wherein we can determine the best answer, I will go on and share my thoughts on how she could improve the results of her survey.

Since she just surveyed her ballet class, she should opt for surveying on other classes with other genres. This would entail reliability and validity and eliminate bias about the results.
