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

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.
