CHEMISTRY – New – with sound!! Hey guys, here’s the lecture from Tuesday on accuracy, precision and percent error. Keep that formula for percent error handy, you’ll be using it all year! We’ll finish discussing significant figures tomorrow. You’ve made a great start on learning to measure with sig figs, so now let’s crank it [...]

HON CHEMISTRY – So which is more important, accuracy or precision? Good question! Here’s the lecture from Monday on just that (the upload acted a little hinky – holler if it won’t open). Don’t lose that percent error formula – you’ll use it all year! And then, drum roll please, just what you’ve been waiting [...]
