Random vs. Systematic Error | Definition & Examples

    https://www.scribbr.com/methodology/random-vs-systematic-error/
    Systematic errormeans 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. Systematic error is also referred to as bias because your data is skewedin standardized wa… See more
