Which data collections show bias? Check all that apply. An English teacher polls the top-ten most avid readers to find their favorite books. An insurance company polls drivers of sports cars to find their average number of tickets. A restaurant manager surveys every tenth customer for one week. An assistant principal surveys each student who is sent for discipline. A fundraiser organizer draws five names from a hat that contains all entries.
The English teacher, restaurant manager, and assistant principal show bias. The data collection for each survey is only gathering data from one small portion of the total population that could be surveyed.
