Examining errors our goal: obtain an estimate of the uncertainty in measured results the plan: 1classify errors 2identify sources of errors 3remove errors we can correct. Errors and uncertainty error has to do with uncertainty in measurements that nothing can be done about if a measurement is repeated, the values obtained will differ and none of the results can be preferred over the others.
