58 Measurement Lab! Follow all directions on the lab sheet. Read directions at least 2x before asking me a question. Answer the questions on your own sheet of paper. Data can be written on the handout. Mass #1-4, volume #5-9, and Questions #10-11

59 BellWork, Thurs 8/24 Which of these pictures shows accuracy?
Which of these pictures shows precision? D A B C

60 BellWork, Thurs 8/24 Which of these pictures is most accurate?
Which of these pictures shows precision?

61 A. Accuracy vs. Precision
Accuracy - how close a measurement is to the accepted value Precision - how close a series of measurements are to each other ACCURATE = CORRECT PRECISE = CONSISTENT

62 B. Percent Error your value accepted value
Indicates accuracy of a measurement your value accepted value

63 B. Percent Error % error = 2.9 %
A student determines the density of a substance to be 1.40 g/mL. Find the % error if the accepted value of the density is 1.36 g/mL. % error = 2.9 %

64 C. Significant Figures Indicate precision of a measurement.
Recording Sig Figs Sig figs in a measurement include the known digits plus a final estimated digit 2.35 cm
