Systematic error occurred due to poor calibration of instrument that can be corrected by


ANSWER

replacing instruments


SOLUTION

Systematic error (also called systematic bias) is consistent, repeatable error associated with faulty equipment or a flawed experimental design. These errors are usually caused by measuring instruments that are incorrectly calibrated or are used incorrectly. However, they can creep into your experiment from many sources, including:

  • A worn out instrument. For example, a plastic tape measure becomes slightly stretched over the years, resulting in measurements that are slightly too high.
  • An incorrectly calibrated or tared instrument, like a scale that doesnt read zero when nothing is on it.
  • A person consistently takes an incorrect measurement. For example, they might think the 3/4 mark on a ruler is the 2/3 mark.
