  "id": "MLC-T-CHM-006637",
  "term": "Linearity of calibration",
  "field": "Chemistry",
  "definition": "The degree to which a calibration curve, which plots instrument response against known concentrations of an analyte, approximates a straight line. A linear calibration indicates a proportional relationship between the analyte concentration and the measured signal within a specific range. This property is assessed using statistical methods like regression analysis.",
