Sampling Methods and Representation

Jaylen wants to find out how much time eighth graders spend on sports by surveying the girls' soccer team. However, this method is not a random sample because it doesn't give all eighth graders an equal chance of being selected, isn't chosen randomly, and doesn't represent the entire population. A random sample requires equal selection chances, random choice, and population representation.

What is a key requirement for a sample to be considered random?

• It must be chosen by a teacher

Why is it important for a sample to represent the entire population?

• To ensure the results are biased
