What is percent error calculation used to determine?
Take the difference between your experimental value and your known value, and divide that difference by your know value. Say you experimentally found the force of gravity to …be 8m/s 2 , and you know that the true/known value is 9.8 m/s 2 , the percent error would be l 8 - 9.8 l = 0.1836 or 18.36% 9.8
It is a measure measurement of the amount of error made in an experiment. It is obtained by comparing the actual result, with the result gotten from the experiment. % error …= [(experimental value - true value) / true value] x 100
you take the actual minus the theoretical number and divide that by the actual number and multiply it by 100.

i want ot say 1 in 8 but the codes have changed since all the brigde failures and i do not know

Determinate error is an error that is caused by the improper functioning of the instrument.These type of errors can be avoided by using an instrument that works properly.
Take the correct value, subtract the value you got, and then divide that figure by the correct value. Then take the absolute value of that and multiply by 100. For example, sa…y I weighed something and got that it was 2.5 grams, but it really was 2.7 grams. 2.7-2.5=.2. .2/2.7=.074. .074*100=7.4. Thus, I had 7.4% error. Another example: 16-15=-1. -1/15=-.067. .067*100=6.7% error.
Percentage error = Value experimental -Value accepted . Value accepted x 100

The definition of error is: difference between the accepted true value and the measured value of a quantity or parameter. But this is the absolute error . The relative (p…ercent error) is: (measured value - accepted true value) . 100/accepted true value This value is exprssed as a percentage - %.
To use it follow this. For example, if you want 100 minus 30% You would put: 1 0 0 X 3 0 % - If you want 100 plus 30% 1 0 0 X 3 0 % +
The more precise your instruments of measurement are, the less percentage of error you will have.
(absolute error)/(full scale deflection) x 100 = % error
Percent by mass = (100) times (mass of the ingredient of interest) divided by (mass of the whole mixture)
