What is the percent error formula?

Answer 1

Percent Error is the difference between the true value and the estimate divided by the true value and the result is multiplied by 100 to make it a percentage. The percent error obviously can be positive or negative; however, some prefer taking the absolute value of the difference.

The formula is the absolute value of the experimental value (minus) the theoretical value divided by theoretical value times 100.

% error = (|Your Result - Accepted Value| / Accepted Value) x 100

Answer 2

the difference between the true value and the estimate divided by the true value. The result is multiplied by 100 to make a percentage

* * * * *

Nearly correct. It is the estimated (or measured) minus the true value, the difference divided by the true value and then the result multiplied by 100 to make it a percentage.

Answer 3

For any percent error formula:

100 x (Experimental Value - Theoretical Value) / Theoretical Value

Take the absolute value of this (make it positive) , and give it a percent sign.

Example: The listed mass was 1 gram, and you found it to be .9 grams

100(0.9-1)= -10

-10/1 =-10

-10 becomes 10

10% error

You will NEVER have a negative percent error, and its a good idea to write "error" after the percent sign.

Answer 4

The percent error formula is:

[ \text{Percent Error} = \left| \frac{\text{Measured Value} - \text{Actual Value}}{\text{Actual Value}} \right| \times 100% ]

It is used to quantify the difference between a measured value and the actual (true) value.

Answer 5

A Percentage Error Is An Estimated Value In Percentages That are not Quite True but you made no mistakes, its just the way of math

Answer 6

Error = Observed value - True Value.

Answer 7

It is absolute error divided by actual measurement multiplied by 100

absolute error=1/2(actual measurement)

Answer 8

It is 600
