F-tests: How to set up contrasts and how they relate to t-tests

If this topic was already covered on my channel, I can't find it :) Here I talk about the F-test. Specifically, how is the statistic estimated using matrix math, what's the interpretation, and how does it relate to t-tests. I have a fun example that explains why your significant F-test may or may not match up with significant t-tests that construct that F-test!
