Detailed explanation-1: -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.
Detailed explanation-2: -Systematic error means that your measurements of the same thing will vary in predictable ways: every measurement will differ from the true measurement in the same direction, and even by the same amount in some cases.
Detailed explanation-3: -Experimental errors There are two types of experimental error: Random error. Systematic error.
Detailed explanation-4: -Typical causes of systematic error include observational error, imperfect instrument calibration, and environmental interference. For example: Forgetting to tare or zero a balance produces mass measurements that are always “off” by the same amount.
