Question

School newspaper staff went to three different sports games to survey students on their favorite sport, and the results are shown in the table below. Are these samples biased? Why or why not? Favorite Sport Survey Sample 1 Sample 2 Sample 3 Basketball 23 Basketball 1 Basketball 1 Football 2 Football 24 Football 2 Volleyball 0 Volleyball 0 Volleyball 22

Answer 1

The results are biased.

When you go to a particular sporting event and ask someone their favorite sport, they are more likely to respond the sport that they're watching at that moment. This creates bias.

Answer 2

Yes, the results are biased.

Explanation:

It is given that:

School newspaper staff went to three different sports games to survey students on their favorite sport.

The results of the survey is given as:

Sample 1 Sample 2 Sample 3

Basketball 23 1 1

Football 2 24 2

Volleyball 0 0 22

These samples are biased because the newspaper staff went to a basketball game, football game, and volleyball match to interview the students he hasn't surveyed the random people as the people who have gone to watch the game are obvious that they would love that game.
