Question

The entertainment committee at Maplecrest Junior High School has narrowed down the theme of the Spring Dance to three choices. The ten committee members want to conduct a survey to determine which theme Maplecrest's 200020002000 students prefer. There will be three choices (Disco Fever, The Crazy Eighties, or Hip Hop Til You Drop) and the committee will go with the theme that gets the most votes.

Answer 1

Survey option 2 is the right survey method that will allow the committee to make a valid conclusion about which theme Maplecrest's student body prefers.

Assign a number to each student, and use a computer program to generate 100 random numbers between 1 and 2000. Ask those students whose numbers are selected.

Complete Question

Which of the following survey methods will allow the committee to make a valid conclusion about which theme Maplecrest's student body prefers?

Choose 1 answer:

- Each of the 10 committee members can ask 10 friends to obtain a sample of 100 students.

- Assign a number to each student, and use a computer program to generate 100 random numbers between 1 and 2000. Ask those students whose numbers are selected.

In the first survey option, asking 10 of the committee member to ask 10 of their friends creates a type of bias. As all of these friends are connected through a chain of friend connects to a particular group/cluster of people in the school and there is high chance of bias in the choice of the song picked.

But survey method 2 randomizes the process as much as possible that it eliminates the bias concerns in survey method 1. It is without doubt the better option for obtaining what the students really want.

Hope this Helps!!!
