- 1.3: Accuracy, Precision, and Significant Figures
Significant figures express the precision of a measuring tool. When multiplying or dividing measured values, the final answer can contain only as many significant figures as the least precise value. When adding or subtracting measured values, the final answer cannot contain more decimal places than the least precise value.
22 paź 2024 · Significant figures are used to report a value, measured or calculated, to the correct number of decimal places or digits that will reflect the precision of the value. The number of significant figures a value has depends on how it was measured, or how it was calculated.
27 sie 2023 · Learning Objectives. Determine the correct number of significant figures for the result of a computation. Describe the relationship between the concepts of accuracy, precision, uncertainty, and discrepancy. Calculate the percent uncertainty of a measurement, given its value and its uncertainty.
19 lis 2014 · The term significant figures actually refers to particular digits in a number. These are sometimes called significant digits. In this document we will use the term significant figures to discuss the broader topic. That way we may still say “digit” to draw your attention to a particular digit under discussion.
Summary. Determine the appropriate number of significant figures in both addition and subtraction, as well as multiplication and division calculations. Calculate the percent uncertainty of a measurement. Figure 1. A double-pan mechanical balance is used to compare different masses.
