Meaning
A zero error is a type of systematic error, caused by a measuring instrument not being calibrated.
About Zero Errors
- A zero error may be found when plotting the scatter graph for an experiment where it is known the two variables should be directly proportional but they appear to only in a linear relationship having a y-intercept that is not zero.
- A zero error can be corrected by calibrating the measuring instruments before an experiment.
