No, the absolute error cannot be negative. Absolute error is defined as the absolute value of the difference between the measured value and the true value, which ensures that it is always non-negative. It is calculated as |measured value - true value|, and since absolute values are always positive or zero, the absolute error itself will also never be negative.
A percentage error is 100*(measurement - true value)/true valueThe percentage error is negative if the measured (or calculated) value is smaller that the true value.
