Ray's rule of precision
WebSep 26, 2024 · Defining Significant Digits. A standard rule of thumb is to report the standard uncertainty with at most two significant digits. By example. ± 1.245 → ± 1.2. ± 0.01245 → ± 0.012. ± 1245. → ± 1.2 × 10 3. The next step is to round the average value according to the significant digits in the uncertainty. By example. WebApr 30, 2024 · This range must not exceed ± 0.005 absorbance units (for absorbance values below 1.0 A) or ± 0.005 multiplied by A (for absorbance values above 1.0 A). Therefore, we …
