Question

Which of the following survey methods is least likely to result in statistical bias? Ask every 3rd person you see at the school gym if they like to work out. Ask all the 6th graders what afterschool activity is most popular. Ask a random sample of your friends which candidate they support for school president. Ask a random sample of all students what they would like the school mascot to be.

Answer 1

The survey method that is least likely to result in statistical bias is asking a random sample of all students what they would like the school mascot to be.

Step-by-step explanation:

The survey method that is least likely to result in statistical bias is asking a random sample of all students what they would like the school mascot to be.

The reason for this is that a random sample ensures that every student in the population has an equal chance of being selected. This helps to minimize selection bias and increases the representativeness of the sample.

On the other hand, the other survey methods mentioned in the question, such as asking every 3rd person you see at the school gym or asking a random sample of your friends, may introduce biases due to the non-random selection of participants.
