Question

How would you find out how many sixth through eighth grade students are interested in joining a running club? Explain how to choose a sample that will give you a good representation of a whole population.

Answer 1

To find out how many sixth through eighth grade students are interested in joining a running club, you can conduct a survey among these students. Choose a sample by randomly selecting a certain number of students from the list, ensuring diversity. Contact the selected students to ask about their interest in joining the club and calculate the percentage of interested students.

Step-by-step explanation:

To find out how many sixth through eighth grade students are interested in joining a running club, you would need to conduct a survey or questionnaire among the students in these grades. Here's how you can choose a sample that will give you a good representation of the whole population:

1. Start by listing all the sixth through eighth grade students in your school.
2. You can then use a random sampling method, such as drawing names out of a hat or using a random number generator, to select a certain number of students from the list.
3. Ensure that the sample includes a diverse group of students, representing different genders, ethnicities, and interests.
4. Contact the selected students and ask them if they would be interested in joining a running club.
5. Record their responses and calculate the percentage of students who are interested in joining the club.

Answer 2

The sample should be a random sample from the entire set of students and should include enough students to be reliable. Small samples have more variation, which leads to less reliable inferences.
