meetwijze

Meetwijze, in Dutch usage, denotes the method or approach used to measure a quantity or property. The term combines meten ("to measure") and wijze ("way"), and it is used across science, engineering, and research to describe how data are collected and quantified.

A meetwijze typically includes the instrument or device, the measurement procedure, calibration steps, sampling strategy, data recording, and the analysis method. It is chosen to maximize validity and reliability while balancing practicality, safety, and cost.

Key criteria include validity (the extent to which the method measures what it should), reliability (consistency of results), accuracy and precision, sensitivity, and specificity. Repeatability and reproducibility are important aspects when measurements are performed by different operators or at different times. Feasibility and resource requirements also influence the choice of meetwijze.

Examples span multiple fields: length or mass is measured with calibrated tools; chemical concentrations with spectrophotometry or chromatography; biological assays with standardized protocols; and social research with structured questionnaires. In manufacturing, inline sensors and sampling plans are common meetwijzen for quality control.

Documentation and standards are common in professional practice. Meetwijzen are described in standard operating procedures (SOPs) and aligned with international or national standards (for example ISO or NIST guidelines) to ensure traceability and comparability of results.
