Sometimes a correction can be applied to a result after taking data to account for an error that was not detected. The smallest divisions on the scale are 1-pound marks, so the least count of the instrument is 1 pound. Systematic errors: These are errors which affect all measurements alike, and which can be traced to an imperfectly made instrument or to the personal technique and bias of the observer. Calculate the uncertainty in this set of measurements.

It is perfectly fine to have percentage error>percentage uncertainty. Systematic Error - Längd: 13:11. You can only upload files of type PNG, JPG, or JPEG. Then, divide by 100 = 1.00001, or 0.001% error.

The experimenter may measure incorrectly, or may use poor technique in taking a measurement, or may introduce a bias into measurements by expecting (and inadvertently forcing) the results to agree with
