How can we minimize error |
Answer» \tType of ErrorExampleHow to minimize itRandom errorsYou measure the mass of a ring three times using the same balance and get slightly different values: 17.46 g, 17.42 g, 17.44 gTake more data.\xa0Random errors\xa0can be evaluated through statistical analysis and can be reduced by averaging over a large number of observations.Systematic errorsThe cloth tape measure that you use to measure the length of an object had been stretched out from years of use. (As a result, all of your length measurements were too small.)The electronic scale you use reads 0.05 g too high for all your mass measurements (because it is improperly tared throughout your experiment).Systematic errors\xa0are difficult to detect and cannot be analyzed statistically, because all of the data is off in the same direction (either to high or too low). Spotting and correcting for systematic error takes a lot of care.How would you compensate for the incorrect results of using the stretched out tape measure?How would you correct the measurements from improperly tared scale?\t | |
