Significant Figure [ENDORSED]

[yoonjong_han_3F]

Do we need to know rule of significant figure for quiz??

[Danny Nguyen 2H]

I think it's always safe to know significant figures and plus I heard for Lavelle's class he emphasizes a lot on sig figs. So I recommend you to review them.

It would be ideal I heard you may lose points for incorrect significant figures.

Can someone post the exact rules for significant figures or does anyone know where I could find them?

[Huongly Do 3D]

If I remember correctly, if you took Chem 14A with Lavelle, or know someone who has the old course reader on them, there should be one/two pages in the front of the course reader that specifically highlights what he expects from us for sig.figs. Additionally, I think the maximum points that can get deducted from our quiz score for not having correct significant figures is 2 points.

Also, if you do not have the Chem 14A Course Reader and do not know anyone who has it, there is the same two pages about sig fig rules in our current Course Reader. It is on pages 122 and 123 immediately following the practice quizzes.

[Diego Zavala 2I]

For rounding a number that ends in 5 (i.e 768.8465), round up iff the number preceeding 5 will become even and truncate iff the number preceeding 5 is already even

Ex. 0.98775 -> 0.9878
Ex. 0.98765 -> 0.9876
