Thread: Contraceptive Experiment Help

Hi guys, im new to this forum and im wondering whether you guys had an idea of how to come up with an experiment on contraceptives. I have to plan an experiment to test the effect of introducing contraception on the average family size in a rural village. Err.. and they do not have any access or knowledge of any contraception.
i am having a tough time on planning a experiment on this and making a method. So if any of u guys can give me any tips or ideas i would appreciate it.
