Degrees of Freedom Explanation - Why We Use n-1 (Week 11B)

Using a classic outer space example with Martians and Robots, we will adjust our interval calculations by subtracting 1 from our sample size (n-1). We take a brief detour to figure out what are degrees of freedom and why we use n-1. Degrees of freedom are the number of independent pieces of information that go into our calculations. When we estimate a population mean from a sample, we lock down one parameter and reduce our degrees of freedom by 1.
