WebJun 24, 2024 · You made a mistake in your error propagation equation. You want to see how an error Δ x propagates and gives rise to a Δ y. It should be something like Δ y = 2 x Δ x which can be rewritten as Δ y / y = 2 Δ x / x. So as usual with multiplication you're adding the relative errors in first order. Share Cite Improve this answer Follow In statistics, propagation of uncertainty (or propagation of error) is the effect of variables' uncertainties (or errors, more specifically random errors) on the uncertainty of a function based on them. When the variables are the values of experimental measurements they have uncertainties due to measurement limitations (e.g., instrument precision) which propagate due to the combination of variables in the function.

If Q = Q(x) is any function of xthen the general formula for error propagation can be defined as: δQ = dQ/dX δx Note that you’ll rarely have to derive these formulas from scratch, but it can be good to know the general formula used to derive them. See more If Q= a + b + … + c – (x + y + … + z) Then δQ = √(δa)2 + (δb)2 + … + (δc)2 + (δx)2 + (δy)2 + … + (δz)2 Example:Suppose you measure the length of a person from the ground to their waist as 40 inches ± .18 inches.
