As a domain expert in experimental physics and data analysis, I can certainly provide an in-depth explanation on the concept of percent error and the possibility of exceeding 100% error in experimental results. It's crucial to understand that percent error is a measure of the difference between a measured or calculated value and the true or accepted value, expressed as a percentage of the true value.
Percent Error Calculation:
The formula for calculating percent error is as follows:
\[ \text{Percent Error} = \left( \frac{\text{Measured Value} - \text{True Value}}{\text{True Value}} \right) \times 100\% \]
Understanding Percent Error:
- A positive percent error indicates that the measured value is greater than the true value.
- A negative percent error indicates that the measured value is less than the true value.
- A percent error of 0% means the measured value is exactly equal to the true value.
Exceeding 100% Error:
Yes, it is indeed possible to have a percent error exceeding 100%. This occurs under specific circumstances:
1. **When the Measured Value is Twice the True Value:** As mentioned in the reference content, a percent error of 100% is obtained when the experimental value is exactly twice the true value. If the experimental value is more than twice the true value, the percent error will exceed 100%.
2. **Significant Human or Experimental Errors:** In practice, due to various factors such as human error, faulty equipment, or incorrect methodology, it is possible to record values that are significantly different from the true value. If a mistake leads to a value that is, say, three times the true value, the percent error would be 200%.
3. Negative Measured Values: If for some reason (which is usually a serious mistake in the experiment) a negative value is measured when a positive true value exists, the percent error can become extremely high, even approaching infinity if the true value is not zero.
Implications of High Percent Error:
A high percent error, especially one over 100%, is a red flag that indicates a potential problem with the experiment. It suggests that there may be significant inaccuracies or errors in the experimental procedure or in the measurement process. It's essential to review the methodology, check the equipment, and ensure that the experiment is conducted correctly to obtain a more accurate result.
Addressing High Percent Error:
When a high percent error is observed, the following steps are typically taken:
- Review the Experiment: Go through the experimental procedure to identify any potential sources of error.
- Check Equipment: Ensure that all measuring devices are calibrated and functioning correctly.
- Repeat Measurements: Take multiple measurements to account for random errors and calculate an average.
- Analyze Data: Use statistical methods to determine the reliability of the results.
Conclusion:
In conclusion, while a percent error over 100% is not common, it is a possibility that reflects significant discrepancies between experimental findings and true values. It serves as a critical indicator that demands a thorough investigation and correction of the experimental process.

Yes, a percent error of over 100% is possible. A percent error of 100% is obtained when the experimental value is twice the value of the true value. In experiments, it is always possible to get values that are way greater or lesser than the true value due to human or experimental errors.Aug 6, 2016
