Secondly, because our time was restricted, we were only able to receive 30 different pieces of data from 30 different people. 30 is a large number, but it would be much more statistically accurate if we took data from much more people. our school has nearly 2000 students. If we took about 200 (or 10% of all) students for our sample, we would have received data that reflected the student population of the school much better (rather than simply taking data from one class like AP Biology)
