Chemistry 8-29-12 Accuracy & Precision
CHEMISTRY – Hey guys, here’s the super fast lecture from Wednesday 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 (we did that during the unit on lab stuff!), 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!!)
P.S. Are you ready for the SI quiz tomorrow? Don’t forget to study SI prefixes and their meanings, SI quantities and their symbols, and the SI units used to measure those quantities. Be proactive in your studying. For heaven’s sake, don’t just read the list – ake flashcards, use quizlet.com, get someone to call them out to you! Good luck!
