📊 Common Error Types

Error Type Definition Formula When to Use
Absolute Error Difference between measured and true value Δx = |xmeasured - xtrue| When you need the actual error amount
Relative Error Absolute error relative to true value Δx/xtrue Comparing errors of different magnitudes
Percentage Error Relative error expressed as percentage (Δx/xtrue) × 100% Standardized error reporting
Instrument Error Error from measurement device limitations Manufacturer specification When using calibrated instruments
Systematic Error Consistent, predictable error N/A Calibration issues, experimental setup
Random Error Unpredictable variations Statistical analysis Repeated measurements

Note: The maximum error represents the worst-case scenario within the specified confidence level.

📚 Precision Measurement Tips

🔧

Instrument Calibration

Regularly calibrate your instruments against known standards to minimize systematic errors.

📊

Multiple Measurements

Take several measurements and use the average to reduce random errors.

👀

Parallax Avoidance

View measurement scales directly from above to prevent parallax errors.

🌡️

Environmental Control

Control temperature, humidity, and vibrations that may affect measurements.

⏱️

Time Considerations

Allow instruments to stabilize and account for response times in measurements.

📝

Error Documentation

Always record error estimates alongside measurements for proper interpretation.
