Can a percentage error be negative?

The percentage inaccuracy can be negative. Positive percent mistakes are common in some applications, whereas negative percent errors are common in others, such as chemistry.

Percent error is important in experiments and calculations using known values since it allows you to check the accuracy of your calculations. Percent error is straightforward to calculate: subtract the actual value from the experimental value, divide by the actual value, and multiply the entire product by 100.

A percent inaccuracy of 0 means that the experimental value and the actual, accepted value are identical. The difference between experimental and actual findings is an absolute value, hence percent mistakes are frequently positive. When determining error is critical, but the direction of the fault makes little difference, this is the case. However, in other cases, the direction of the divergence is critical.

Negative percent error numbers are common in chemistry and other sciences. A reaction between two chemicals, for example, may have a previously documented final yield. It is critical that any scientists who execute this response report on its precision. It’s also crucial to understand the error’s direction. A higher-than-expected yield implies a positive percent error, whereas a lower yield shows a negative percent error.
