Question 460883: A convenience store asked every 21st person who entered the store for a week, their opinion of the automatic checkout machines. Is this an unbiased sample? Give a reason for your conclusion. Answer by richard1234(7193) (Show Source):
You can put this solution on YOUR website! From the standpoint of one who has never taken statistics, I would say it is unbiased because the feedback from the customers should have no correlation with the customers' positions in line.
