Mittauser Avuuudet, a Finnish term often translated as "measurement uncertainties" or "measurement errors," refers to the inevitable deviations from the true value of a quantity that occur during any measurement process. These uncertainties are inherent to all measurements and arise from a variety of sources, including limitations of the measuring instruments, environmental factors, and the skill of the observer.

Understanding and quantifying measurement uncertainty is a fundamental aspect of metrology, the science of measurement. It is crucial for ensuring the reliability and validity of experimental results, for comparing measurements made by different individuals or laboratories, and for making informed decisions based on measured data. Without an assessment of uncertainty, a measurement value alone can be misleading.

The sources of measurement uncertainty can be broadly categorized. Random errors are unpredictable fluctuations that vary with each measurement. They can be reduced by taking multiple measurements and averaging them, but they cannot be entirely eliminated. Systematic errors, on the other hand, are consistent and repeatable deviations from the true value. These can arise from miscalibration of instruments, flawed experimental procedures, or inherent biases. Identifying and correcting systematic errors is important, though often challenging.

Reporting measurement uncertainty typically involves providing a numerical value, often expressed as a standard deviation or a range, that defines the interval within which the true value is expected to lie with a certain level of confidence. This allows users of the measurement data to assess the quality and trustworthiness of the results.
