Saktësie

Saktësie is a term used to describe the quality of being correct, true, or exact. In everyday language it refers to how free a statement or result is from error, while in scientific and technical contexts it denotes how closely a measurement, calculation, or assessment corresponds to the true value or standard.

In metrology and data quality, saktësia measures the agreement between observed values and the real value. High saktësie means measurements approximate the true quantity with minimal systematic bias. Factors that affect saktësia include calibration, instrumentation limits, environmental conditions, and methodological choices. It is often discussed alongside uncertainty and error analysis, which quantify the range within which the true value is expected to lie.

A common distinction in many fields is between accuracy and precision. Saktësia specifically relates to closeness to the true value, whereas precision concerns the consistency or repeatability of measurements. An instrument can be precise without being accurate if it yields consistently wrong results, and it can be accurate but not precise if measurements cluster near the true value but show large variability.

Applications of saktësie appear in science, engineering, journalism, and everyday decision-making. Assessing saktësie helps validate tools, methods, and information, and it guides improvements in experiments, reporting, and quality control.
