Interval-independent

Describes a process, measurement, or data point whose value or characteristic is unaffected by the duration or specific timing of the intervals used for observation or analysis. It signifies that the outcome or result remains consistent regardless of how time is segmented. This contrasts with interval-dependent phenomena, where time intervals directly impact the results. interval-independent attributes are stable across different time frames and granularities, emphasizing inherent characteristics rather than external influences.

Interval-independent meaning with examples

• A perfectly elastic spring demonstrates interval-independent behavior. Its compression distance is solely determined by applied force, not how quickly the force is applied or the time allowed for compression. This predictability holds irrespective of whether the force is applied over seconds, minutes, or hours.
• The boiling point of water at standard atmospheric pressure is interval-independent. It will consistently boil at 100°C, regardless of how frequently or over what duration heat is applied. The time to reach boiling is interval-dependent, but the boiling point itself is not.
• A person's height, a genetic trait, is largely interval-independent. The measurement result is fixed by genetics, and is not directly affected by their time spent in a given position. However, some measurements may have intervals dependent on external forces.
• Consider a digital image's pixel values. As long as the image remains the same, these values are interval-independent. Changing the way these pixel values are processed using filters, or analyzing them in different time frames has little or no effect.
• The radioactive half-life of a specific isotope is interval-independent. It reflects the inherent decay rate, irrespective of how frequently measurements are taken or the intervals between them. The remaining amount will be the same every time.
