Crash Course: Statistics #20 - Confidence Intervals

Today we’re going to talk about confidence intervals.

Confidence intervals allow us to quantify our uncertainty, by allowing us to define a range of values for our predictions and assigning a likelihood that something falls within that range. And confidence intervals come up a lot like when you get delivery windows for packages, during elections when pollsters cite margin of errors, and we use them instinctively in everyday decisions. But confidence intervals also demonstrate the tradeoff of accuracy for precision – the greater our confidence, usually the less useful our range.
