Täpsuseid

Täpsuseid is the Estonian word referring to the concept of accuracy or precision as used in measurement, statistics, engineering, and related fields. The term is the plural form of täpsus, which denotes the quality of being exact or correct.

In metrology and measurement theory, täpsus describes how close a measured value is to the true value. It is influenced by systematic errors (bias) and random errors, and is commonly expressed through margins of error, confidence intervals, and calibration uncertainty. Higher täpsus implies smaller total measurement error.

In data analysis and computer science, täpsus often appears in discussions of model evaluation. Depending on the context, it can refer to accuracy—the proportion of correct predictions among all predictions—or to precision as a component of the confusion matrix, describing the proportion of true positives among positive predictions. The exact usage can vary by discipline and language conventions.

Achieving higher täpsus requires careful experimental design, good instrumentation, proper calibration, and rigorous data handling. It may involve statistical methods for estimating uncertainty, performing calibration against reference standards, and minimizing bias.

In practice, researchers report täpsus alongside uncertainty estimates, calibration procedures, and documented limitations, to provide a transparent assessment of measurement or prediction quality. See also related concepts such as accuracy and precision in measurement and data analysis.
