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 %
