Question

Relation between standard deviation and percentage uncertainty

Answer 1

Hope this helps you mark as brainlist if you satisfied with the ans



Usually you would measure and report an average and a standard deviation. From these you can derive all others. The reason to calculate a variance is to use it in follow-up calculations. When you add numbers, you also have to add their variances to find the new variance. You should not add standard deviations. The reason to calculate a percentage uncertainty is: 1. To get a sense how accurate the measurement is. As a rule of thumb an uncertainty of less than 2% is deemed negligible. 2. To use in follow-up calculations. When you multiply with a number, the uncertainty of the product is that number multiplied by the percentage uncertainty.❤️❤️❤️
