mõõtemääramatust
Mõõtemääramatust, also known as measurement uncertainty, is a fundamental concept in metrology, the science of measurement. It quantifies the doubt about which value an unknown measurement result is most likely to be close to. This concept is crucial for ensuring the reliability and repeatability of measurements in various fields, including science, engineering, and industry.
Measurement uncertainty is typically expressed as a range of values within which the true value of a
Several components contribute to measurement uncertainty, including:
1. **Random errors**: Variations in measurements due to unpredictable factors, such as environmental conditions or instrument
2. **Systematic errors**: Consistent deviations from the true value, often due to instrument calibration or measurement
3. **Influence quantities**: External factors that affect the measurement process, such as temperature or humidity.
To estimate measurement uncertainty, metrologists use various methods, including statistical analysis, calibration procedures, and the Guide
Understanding and quantifying measurement uncertainty is essential for making informed decisions, validating results, and ensuring the
