Experimental Uncertainty |
|
Experimental tests are often used to acquire data for engineering purposes. Even with precise instrumentation and careful procedures, the final results of such tests are inherently subject to some degree of error. It is becoming increasingly important to know the bounds of such error, yet more often than not, this information is not available. Experimental Uncertainty analysis is a mathematical procedure that accounts for random errors and quantitatively determines their cumulative effect on the overall test results. Although this analysis can be done after completing a test, ideally it should be performed during the planning stage. This will pinpoint sources of unacceptable error while there is time to implement improvements in the procedure or instrumentation. |
