A hi school is conducting a survey to see how many students have part time jobs. Would this sample be biased or unbiased?
nalin [4]
It would be biased because one would assume that students can get to school by means other than those that put them 8n the parking lor.

The freshmen/sophomores would be excluded generally as they would be too young to drive altogether
