    Measurement is the process of quantifying physical quantities using defined units and standards. Understanding key terminologies in measurement is essential for accuracy, consistency, and reliability in engineering and scientific applications.
    Key Terms in Measurement:
    Accuracy: The closeness of a measured value to the true or accepted value. It reflects the correctness of a measurement.
    Precision: The degree of repeatability or consistency of measurements under unchanged conditions. High precision indicates closely grouped results.
    Calibration: The process of comparing a measurement instrument to a standard reference to identify and correct deviations.
    Standard: A reference against which measurements are compared. Standards can be international, national, or working standards.
    Error: The difference between the measured value and the true value, expressed as systematic, random, or gross errors.
    Sensitivity: The smallest change in a quantity that a measuring instrument can detect.
    Resolution: The smallest increment of measurement that an instrument can display.
    Range: The span between the minimum and maximum values a measuring instrument can measure.
    Traceability: The ability to relate individual measurement results to national or international standards through an unbroken chain of comparisons.
    Repeatability: The ability of a measurement system to produce consistent results under the same conditions over repeated trials.
    Significance:
    Understanding these terms helps ensure accurate measurements, proper instrument selection, and adherence to quality standards. It facilitates effective communication among engineers and scientists, contributing to reliable outcomes in research and industry.
