You want to determine the average number of songs people keep on their MP3 players. You want to collect data from a random sample of at least 300. Which of these would be the most valid method of collecting data?

a. Survey students coming in and out of your school cafeteria.

b. Survey an equal number of students, teachers, parents, and grandparents.

c. Survey the residents in a retirement community.

d. Survey the people coming in and out of the grocery store on a Sunday morning.

I think it's D. But I'm not sure.

I don't like any of those choices.

How many young people go to the grocery store on Sunday morning?

B is the best way of getting a random sample. However, you'd probably get a "HUH?" from older people.
