10290491181	Accuracy	correctness; agreement of a measurement with the true value	0
10290491182	Precision	reproducibility; degree of agreement among several measurements.	1
10290495633	Random Error	equal probability of a measurement being high or low	2
10290495634	Systemic Error	occurs in the same direction each time	3
10290504171	Non-zero digits	Always significant	4
10290506679	Significant zeros	- The zero in question is "terminating AND right" of the decimal [must be both] - The zero in question is "sandwiched" between two significant figures	5
10290512428	Sig Fig rule for multiplying and dividing	the term with the least number of significant figures determines the number of maximum number of significant figures in the answer.	6
10290513869	Sig Fig rule for adding and subtracting	the term with the least number of decimal places determines the number of significant figures in the final answer.	7
10290524245	Meniscus	bottom of liquid curve where volume is read	8
10290527755	neither precise or accurate		9
10290532772	both precise and accurate		10
10290532606	precise but not accurate		11
10290541388	Leading zeros	-zeros that precede all nonzero digits -do not count as significant	12
10290548981	Captive zeros	- zeros between nonzero digits - always considered significant	13
10290553116	Trailing zeros	- zeros at the right end of the number - significant only if number has a decimal	14
