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. WebJun 15, 2024 · An exception to this rule occurs when multiplying a number by an integer, as in 12.793 × 12. In this case, the number of significant figures in the answer is determined by the number 12.973, because we are in essence adding 12.973 to itself 12 times. The correct answer is therefore 155.516, an increase of one significant figure, not 155.52.

WebWhen summaries have higher precision than the data, write the values in a way that reflects that extra precision. For instance, a mean of n values has n times the precision of the individual values: roughly, include one extra significant figure for 3 ≤ n ≤ 30, two for 30 < n ≤ 300, etc. (This is rounding on a log-10 scale, obviously.)
