- [Instructor] Election time,…polls, polls, polls, polls, polls.…You get it.…They're essentially just predictions…of which candidate is going to win.…Maybe you pay attention to this stuff,…but do you know much about how the data is collected?…I'll tell you this,…a lot of the analysis is based on inadequate sample sizes,…which means that prediction polls…really don't mean much of anything.…When you watch election coverage on TV…I bet you say to yourself,…"Oh man, I cannot believe that candidate Y is winning,"…but are they actually winning in reality?…No, it's just a prediction based on who knows what…kind of methodology.…
The news team doesn't really want to bore you…with the technical information that actually matters…on the backend.…They want you to feel emotion so that you're hooked…and you keep watching.…What about the stock market?…Analysts pour over data to predict…how the market is going to behave,…but the reality is that future models of the stock market,…and economic behavior in general,…are unreliable.…Economic events may span several years…
