You want to determine the average number of text messages that students at your school send in a month you want to collect data
from a random sample of at least 200 students which of these would be the most valid method for collecting data? Hand out and collect surveys in all of the freshman homerooms
Hand out and collect surveys at a football game
Hand out and collect surveys from all of the teachers
Hand out and collect surveys from students in the hallways
I would go with football or hallway. If you choose footbal you would probably get a more random demographic but you might not get 200. If you choose hallways you could get 200 so hallway is probably more likely
