There are a lot of events in life that we just can't predict, but just because something is random doesn't mean we don't know or can't learn anything about it.
========== Hi, I’m Adriene Hill, and Welcome back to
Crash Course, Statistics. There’s a lot of talk of “randomness”
in statistics. It’s probably something you’ve heard a
lot in this series and in real life too. Randomness is tied to the idea of uncertainty. Like why are these fries here? And are they delicious? But just because something is random doesn’t mean we know nothing about it. For example, I might not know exactly how
many people will shop at my local Costco today, but I do know it’s probably more than 100,
and probably less than 1 million. Even with these very conservative guesses,
I still know something about the “randomness” of this variable. It’s an odd juxtaposition of what we know
and what we don’t at the same time. INTRO Lots of things in your everyday life...
