Mittauserra, often translated as measurement errors, refers to the discrepancies that occur when measuring a physical quantity. These errors are inherent in any measurement process and can arise from various sources. Broadly, measurement errors are classified into two main categories: systematic errors and random errors.

Systematic errors are consistent and predictable deviations from the true value. They often arise from flaws in the instrument itself, such as miscalibration, or from constant environmental factors affecting the measurement. For example, if a scale consistently reads 5 grams heavier than it should, that is a systematic error. These errors can often be identified and corrected, either through recalibration or by adjusting the measured values.

Random errors, on the other hand, are unpredictable fluctuations in measurements. They are caused by transient, uncontrolled factors such as variations in environmental conditions, limitations of the observer's perception, or inherent variability in the system being measured. Unlike systematic errors, random errors cannot be easily predicted or eliminated. However, their impact can be reduced by taking multiple measurements and calculating the average. This averaging process helps to cancel out the random fluctuations, leading to a more reliable estimate of the true value.

Understanding and quantifying measurement errors is crucial in scientific research, engineering, and many other fields. It allows for the assessment of the quality and reliability of data, enabling more accurate conclusions to be drawn. The field of metrology, the science of measurement, is dedicated to studying and minimizing these errors.
