For questions related to methods, analysis, accuracy, presentation, or interpretation of measurements. It is not intended for abstract quantum measurement questions such as how a wave function collapses during measurement or how the Heisenberg uncertainty principle constrains quantum measurements.

Measurement is the process of quantifying an attribute of an object, event, or system. Scientific measurements always consist of a definition of what is being measured, numerical values for the magnitude and uncertainty of the measured quantity, and the measurement unit.
