IXL | Populations and samples

A baby giraffe was born recently at Hillview Zoo, and the staff members need to name the baby. They narrow their choices down to 5 names and then decide to get the opinions of the zoo's visitors before making the final choice. The staff can't realistically survey every zoo visitor, so each staff member surveys 10 randomly selected visitors one weekend.

question

A video game company wants to know which gaming console most teens between the ages of 13 and 18 own.

key idea

A population is a set of objects or living things that a researcher wants to learn something about.

sample,

or part, of the population.

solution

A video game company wants to know which gaming console most teens between the ages of 13 and 18 own. So the population is all teens 13 to 18 who own a gaming console.

It would be very difficult to ask every teen 13 to 18 who owns a gaming console, so researchers conduct focus groups around the country and survey the teens who participate. This means the sample is the teens who participate in the focus groups.
