Describe why sampling is important to the study of populations.

wells its called epidemiology- the study of people. anyways i believe the reason why we do this is to kind of keep track of the people, i know that epidemiologist keep records of those you in war and die from them, who has a "std"(sexual transmitting disease) and from those you don't, from teens who are with child and those who aren't ... all above these are examples of what can or could be important of studying the population.

and to include on my paragraph above, i would say if we didn't keep track or records we really would be clue less and maybe overly populated and the earth would maybe be gone, and we probably wouldn't even be here today, well thats all what i am saying.
