CHEM 130 Chapter Notes - Chapter R: Trailing Zero, Reproducibility, Significant Figures
Document Summary
Used around the world to make measurements adaptable. Measure of the resistance experienced in a state of motion. A measurement always has some degree of uncertainty. The certain digits and the first uncertain digit. The uncertainty in the last number is usually assumed to be 1 unless otherwise indicated. The agreement of a particular value with the true value. The degree of agreement among several measurements of the same quantity. A measurement has an equal probability of being high or low. Occurs in the same direction each time. Precision is an indication of accuracy only if there are no systematic errors. Exact numbers never limit the number of significant figures in a calculation. Write the number with the significant figures and multiply it by 10 to a certain power. The number of significant figures can be easily indicated. Fewer zeros are needed to write very large or small numbers.
