Real-Life Scenarios

> Text version for animation

Our friends come up with the following designs:

Marissa decides to observe the students in all four lunch shifts at her school. She chooses to document what 25 students per lunch shift bring to lunch each day.

Andrew develops a survey to hand out to 25 students during the four lunch shifts at his school. The survey asks, “Which is better to have in your lunch, an apple or a candy bar?”

Allyson sets up a table in the lunch room. She has a pile of candy bars on one plate and a pile of apples on another plate. At each lunch shift, she invites 25 students to her table and allows them to choose one item (candy bar or apple) for free. She records which item is most chosen.

The three friends have each designed a different statistical study: a survey, an experiment and an observation.
