meetreeks

Meetreeks is a Dutch term that translates to “measurement series” in English. In its broad usage, meetreeks refers to a time-ordered sequence of measurements of a single quantity, collected under defined conditions and with known instrumentation. Such series are used to characterize the quantity, monitor stability over time, estimate measurement uncertainty, and detect changes or anomalies. A meetreeks typically includes a timestamp for each observation, the measured value, and information about the measuring device and calibration state. The data may be sampled at regular intervals or irregular intervals, and may involve recurrent measurements under varying conditions to study effects such as drift, repeatability, and reproducibility.

Quality and preprocessing considerations are central to meetreeksen. Data quality practices emphasize traceability to standards, documentation of the measurement process, and assessment of precision, accuracy, bias, and drift. Preprocessing may involve outlier detection, missing data handling, alignment, normalization, and smoothing. Statistical analyses commonly applied to meetreeksen include time series analysis, trend estimation, autocorrelation assessment, spectral analysis, and control charts.

Applications of meetreeksen are diverse. They appear in manufacturing for process monitoring and quality control, in environmental and climate monitoring, in laboratory experiments and metrological surveys, and in sensor networks and IoT data streams. Analyzing a meetreeks often aims to quantify long-term trends, characterize short-term variability, establish control limits, or compare measurements against reference standards.
