How to Read Survey Data (and How Not To)

Through some of my classes here, I’ve become more interested in the math and science of surveys and polls. I know that some people don’t trust polls, but the more I learn about them, the more fascinating I find them. I’d like to know more about how they work and how people should use them. Experts, what can you tell me about polls and surveys? Why is it that some people don’t trust them? What sort of opportunities are there in terms of careers and research related to polls?
