Calibrate - GCSE Biology Definition

In GCSE Biology, to calibrate means to adjust or check a measuring instrument to ensure it gives accurate and reliable results. Calibration is often done by comparing the instrument’s readings to a known standard or reference. For example, a thermometer might be calibrated using water at 0°C or 100°C to check that it measures freezing or boiling points correctly. Calibration is important in biology experiments because it reduces measurement errors and increases the reliability of the data collected.
