What 6 concepts are covered in the Relative Error Calculator?

absolute error
The difference between the experimental (Actual) value and expected or theoretical value
results or observations that happen in real life
experimental value
the value that is measured during the experiment.
a specified amount in or for every hundred. one part in every hundred.
n% = n/100
relative error
the ratio of the absolute error of a measurement to the measurement being taken.
theoretical value
value determined from theory - what you expect to happen
