WebApr 23, 2024 · In Physics errors are basically the deviation of the actual value from the calculated ones, and they are classified as given below: Systematic Error: these are the errors due to the system. Systematic error is further classified as Instrumental error: Errors that arise due to imperfect design or calibration of the measuring instrument. Eg: WebAbsolute Error = 0.05 m And: Relative Error = 0.05 m12.5 m = 0.004 And: Percentage Error = 0.4% More examples: Example: The thermometer measures to the nearest 2 degrees. The temperature was measured as 38° C The temperature could be up to 1° either side of 38° (i.e. between 37° and 39°) Temperature = 38 ±1° So: Absolute Error = 1° And:
