Oversampling (Or why there’s no Democratic conspiracy in the polls)
One common complaint I’ve heard throughout the internet, mostly among people who think Clinton “rigged the election”, is that the polls were wrong due to oversampling. To people who do not know statistics, “oversampling” sounds like a conspiracy. It seems to imply that the Clinton campaign intentionally sampled too many black people and Hispanics in order to make it look like she had a greater chance of winning. However this is a fundamental misunderstanding of what oversampling is. Oversampling isn’t a way for pollsters to blind themselves about demographics and how they vote. In fact, it’s precisely the opposite.
