Meaning
Experimental Error is mistakes in the results of an experiment that happen because of a problem with the method or the measuring equipment.
About Experimental Errors
- Experimental errors lead to results that are not accurate.
- The smaller the reading or measurement taken, the more important the error becomes. A measurement of 10 seconds with a 0.2 second error is less inaccurate than a 0.5 second measurement and a 0.2 second error.
Experimental error may be:
- A Random Error when a Control Variable that has not be controlled properly.
- A Human Error when a human does not read a measuring instrument properly.

- A Human Error when a human does not read a measuring instrument properly.
- A Systematic Error when the results wrong by the same amount each time.
- A Zero Error, a type of Systematic Error, caused by a measuring instrument not being calibrated.
