To determine the Percent value, you must have two variables: True value, the Recorded or Measured value, and it is represented by the following equation:
(Recorded/Measured value - True value) / True value *100%
e.g (20.000 - 21.571) / 21.751*100% = -7.223%

What term is associated with the reproducibility of an experiment?
percent error :)
A student incorrectly converted 20ºC to 64ºF instead of 68ºF What is the student's approximate percent error?
Error percentage = (error value - theoretical value)/(theoretical value) * 100%You figure out the rest.PS, it looks like a really small percentage.
Mass of a sample measured 9.67gwhat is the percent error if the correct mass is 9.82g?
percentage error= experimental value-accepted value/ accepted value x 100 (percentage error is negative only if the accepted value is larger than the experimental value) percentage error= 9.67-9.82/9.82 x 100 percentage error= -1.6
Why is important to perform several trials of an experiment?
becase it reduces the percent error and it gives a much better idea of what is the best result
What is Refractive error measured in?
Refractive error is measured in units called diopters

How do you calculate percentage error for density of pennies?
Percent error refers to the percentage difference between a measured value and an accepted value. To calculate the percentage error for density of pennies, the formula is given as: percent error = [(measured value - accepted value) / accepted value] x 100.

How do you calculate the mean absolute percent error with a 0 actual value?
By definition of percent error, you can't. But you can approximate zero instead, with the number of decimals appropriate to the accuracy of the measurement, e.g. 0.01, 1E-100, etc.
What is relative errors?
