A town’s athletic league contains 18 baseball teams. The board members of the league want to survey adults attending games to determine if they believe the athletes are showing good sportsmanship. The board members attended one game and surveyed an equal number of adults supporting each of the two teams. Which best explains the validity of the results?
Answer
A
invalid because the sampled adults are not part of the population
B
valid because adults are the target population
C
valid because an equal number of adults supporting both teams were surveyed
D
invalid because of biased sampling
Explanation
The survey includes adults at only one game, so it may not represent adults attending games across all 18 teams. The views of fans at that game could differ from those of other attendees. Surveying equal numbers supporting each team at that one game does not remove this sampling bias. Therefore, the results are invalid because of biased sampling.
