The measurement error is defined as AX=X-Xo.where Xo is the true value of a physical quantity. X is
the measured value of the physical quantity, AX is also known as "absolute error" What is the correct
understanding to absolute error?
Select one:
O a An absolute error indicates the absolute value of the error.
Ob Absolute error is the difference between the measured value and the true value.
O e Absolute error indicates that the error is always positive.
Od. Absolute eror indicates that the magnitude of an error is certain.
Calculate the value of the error with one decimal place for the multiplication of x and
y:
z=xxy
where x = 22 +/-5%
and
Please enter the answer without +/- sign.
y = 15+/-5%
