Noah wants to predict who will be selected as the sixth-grade treasurer for student council. Which of the following groups should Noah survey to make his prediction?

A) The first 100 students from an alphabetical list of the entire school

B) The first 100 students from an alphabetical list of sixth graders

C) One hundred random students from the entire school

D) One hundred random students from the sixth grade

D) One hundred random students from the sixth grade

First off, the survey should be focused on the sixth graders, since they are the demographic that will be voting for 6th grade treasurer.

Next, the group should be random, because random groups better represent the entire class than an alphabetic list. Maybe those first 100 kids in the list like Noah because he has a last name that begins with A or something. It's not likely, but it's something that could corrupt the data collection.

The answer is D ... one hundred random students from the sixth grade
