Percent error.
high percent error is the absolute value of something that is multiplied
Depending on whether you subtract actual value from expected value or other way around, a positive or negative percent error, will tell you on which side of the expected value that your actual value is. For example, suppose your expected value is 24, and your actual value is 24.3 then if you do the following calculation to figure percent error:[percent error] = (actual value - expected value)/(actual value) - 1 --> then convert to percent.So you have (24.3 - 24)/24 -1 = .0125 --> 1.25%, which tells me the actual is higher than the expected. If instead, you subtracted the actual from the expected, then you would get a negative 1.25%, but your actual is still greater than the expected. My preference is to subtract the expected from the actual. That way a positive error tells you the actual is greater than expected, and a negative percent error tells you that the actual is less than the expected.
The formula of percent error ispercent error= Your value/accepted value 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 (percent error) is:(measured value - accepted true value) . 100/accepted true valueThis value is exprssed as a percentage - %.
The span error is calculated by taking the span error and dividing it by the original measurement then multiplying by 100. The value gives us the span error as a percentage.

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.

To ensure results are of optimal percent error, scientists must manipulate only one variable. Therefore, they use controlled experiments.
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.
