Example Question #1 : Census And Studies
Kate would like to determine what flavors of ice cream are most popular among students in her AP Statistics class. In total, there are 100 students in the class. Which of the following would be an appropriate sampling methodology?
Randomly select several of the most popular students in the class to answer questions about their favorite ice cream flavor
Group students into several homogeneous groups and choose one group to survey in order to determine the class's favorite ice cream flavor
There is no effective way to obtain a representative sample from the target population
Obtain a census of the class and survey each person in the class to determine their favorite flavor of ice cream
Ask every fifth person that walks through the door what their favorite flavor of ice cream is before class starts
Obtain a census of the class and survey each person in the class to determine their favorite flavor of ice cream
