"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 … See more In research, systematic errors are generally a bigger problem than random errors. Random error isn’t necessarily a mistake, but rather a natural part of measurement. There is always some variabilityin … See more Random error affectsyour measurements in unpredictable ways: your measurements are equally likely to be higher or lower than the true values.
