Question

The absolute error in a single measurement a_i​ is given by ______.

Options

• Δa_i​ = a_i​ − a_m​

• Δa_i​ = a_m ​− a_i​

• \[\Delta a_i=\frac{a_m}{a_i}\]

• \[\Delta a_i=\frac{a_i}{a_m}\]

Answer 1

The absolute error in a single measurement a_i is given by Δa_i​ = a_m ​− a_i.

Explanation:

Absolute error is the difference between the mean value and that particular measured value; its magnitude is used for further calculations.
