how do i run a sample survey?

OpenStudy (campbell_st):

there are lots of ways a sample means that you survey a small part of the population. random sample: means you select people at random systematic sample you select people using a rule... such as every 10th person who walks through the door. stratified sample take a proportion of the population from each group or strata e.g. a school population, students in year 7, 8, 9 and year 10 if you wanted 50 people then its 50 x year 7/total school population... this way you get a sample that is proportion to the size of the year group in the school. hope it helps
