Julia Asked 100 sixth-grade students at random what their favorite pizza topping is
Tanner Asked 100 third-grade students at random what their favorite pizza topping is
Which student's survey is most likely not biased
Troy
Dacia
Julia
Tanner

Julia's survey is most likely not biased as she asked sixth-grade students at random what their favorite pizza topping is, which is the same grade level as the target group. Asking students from the same grade level reduces the likelihood of bias.
