Although, the error in measurement cannot be entirely eliminated, you can lessen it by taking this precaution. Considering these results, she will report that dispenser #1 is precise (values all close to one another, within a few tenths of a milliliter) but not accurate (none of the values are close to the target value of 296 mL, each being more than 10 mL too low). The ambiguity can be resolved with the use of exponential notation: 1.3 103 (two significant figures), 1.30 103 (three significant figures, if the tens place was measured), or 1.300 103 (four significant figures, if the ones place was also measured). A measurement result is properly reported when its significant digits accurately represent the certainty of the measurement process. Graduated cylinders have a smaller width than beakers. accuracy: how closely a measurement aligns with a correct value, exact number: number derived by counting or by definition, precision: how closely a measurement matches the same measurement when repeated, rounding: procedure used to ensure that calculated results properly reflect the uncertainty in the measurements used in the calculation, significant figures: (also, significant digits) all of the measured digits in a determination, including the uncertain last digit, uncertainty: estimate of amount by which measurement differs from true value, number derived by counting or by definition, estimate of amount by which measurement differs from true value, (also, significant digits) all of the measured digits in a determination, including the uncertain last digit, procedure used to ensure that calculated results properly reflect the uncertainty in the measurements used in the calculation, how closely a measurement matches the same measurement when repeated, how closely a measurement aligns with a correct value. Precise values agree with each other; accurate values agree with a true value. *Always read a graduated cylinder from the bottom of the meniscus. A graduated cylinder is used to measure volume.
