The absolute error of the first measurement (a1) in a set of measured values a1, a2, ..., am is given by:
$$
\text { Absolute error }=\left|a_1-A\right|
$$
Here:
•    a1 is the first measured value.
•    A is the true value or mean value of all measurements

$$
\text { Formula }=A=\frac{\left(a_1+a_2+\ldots+a_m\right)}{m}
$$
Therefore, the absolute error for the first measurement is the absolute difference between a1 and the mean value A.
