How to Calculate Uncertainty | Sciencing
https://sciencing.com/how-to-calculate-uncertainty-13710219.html
WebOct 26, 2020 · If you’re taking a power of a value with an uncertainty, you multiply the relative uncertainty by the number in the power. For example: (5 \text{ cm} ± 5\%)^2 = (5^2 ± [2 × 5\%]) \text{ cm}^2 = 25 \text{ cm}^2± 10\% \\ \text{Or} \\ (10 \text{ m} ± 3\%)^3 = 1,000 \text{ m}^3 ± (3 × 3\%) = 1,000 \text{ m}^3 ± 9\%

WebJul 27, 2023 · Calculate the square of the deviations of each reading. Uncertainty is calculated using the formula given below. Uncertainty (u) = √ [∑ (xi – μ)2 / (n * (n-1))] Uncertainty = 0.03 seconds. 68% of values fall within 1 standard deviation of the mean (-1s <= X <= 1s) So Timing at 68% confidence level = μ ± 1 * u.
