Chemistry 8-30-11 Accuracy & Precision

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 up a notch and begin to calculate with them. Don’t panic about the homework, I’ll show you tomorrow! (Just make sure you try it!!)
