Jane's survey is most likely not biased because she asked sixth-grade students at random what their favorite ice cream flavor is. This method ensures that the survey results are representative of the target population, which in this case is sixth-grade students. Asking seventh-grade, eighth-grade, or third-grade students may introduce bias as their preferences may be different from sixth-grade students.
