Percent Error Negative Math

Significant figures are important in science.

Percent error negative math. 260 325 65 ignore the sign so my error is 65. Ignore any minus sign. Multiply this value by 100 to obtain the percent error. Yes we can calculate percentage error without having absolute value.

0 0074074 x 100 0 74 expressed using 2 significant figures. I estimated 260 people but 325 came. A 5 error could mean that your results were a little. This is the case when it is important to determine error but the direction of the error makes no difference.

A percent error of zero indicates that an experimental value is exactly the same as the actual accepted value. A negative percent error is possible. First find the error. In some situations however the direction of the deviation is important.

Subtract one value from the other. The error will be negative only if the experimental value is less than the accepted value. Percent errors are often positive with the difference between experimental and actual results being an absolute value. If your observed results were lower than the expected then you would have a negative percent error.

If you report an answer using too many or too few it may be considered incorrect even if you set up the problem properly. Percentage error can be either negative or positive. Chemistry and some other sciences maintain negative percent error values. Can we calculate percent error without absolute value.
