english: If our sample is cherry-picked in some way -- say, we poll only urban voters, or say, in our clinical trials for treatments for heart disease, we include only men -- the results may not generalize to the broader population.
non_english: Ako je naš uzorak biran na neki način - recimo, ispitamo samo gradske birače, ili recimo, u kliničkim ispitivanjima tretmana bolesti srca uključimo samo muškarce - rezultati se možda neće generalizovati na širu populaciju.
