It could refer to a discrepancy, irregularity, inconsistency, or something unusual or abnormal in various contexts like statistics, sciences, medicine, and more. This deviation can be either positive or negative, and is often used to detect unusual occurrences or phenomena.

  3. Anomalynoun

    the angle measuring apparent irregularities in the motion of a planet

  4. Anomalynoun

  5. Etymology: [L. anomalia, Gr. . See Anomalous.]

  1. anomaly

    Deviation from common rule.
