MAE 2381 FINAL EXAM QUESTIONS
AND ANSWERS LATEST UPDATE!
FSO Full Scale Operation - ANSWERspecified as a percentage, determines the full
scale value, multiply full scale value and percentage error as a fraction
RDG Reading - ANSWERspecified as a percentage, determine the actual or
anticipated reading, multiply reading and percentage error as a fraction
Least Significant Digit - ANSWERspecified as a percentage, determines least
significant digit in display, multiply least significant digit and error as a fraction
PPM (Parts per Million) - ANSWERconvert to fraction, determine actual or
anticipated reading, multiply reading and error as a fraction
Calibration Error - ANSWERnon perfect measurement instruments- linearity and
sensitivity error
Data Acquisition Error - ANSWERprocedure affecting readings; sequential vs
random sampling
Data Analysis Error - ANSWERmeasurement not providing desired value; curve fit
has confidence interval
Zero Order Uncertainty - ANSWERvariation in results due to analog instrument
resolution only
Instrument Uncertainty - ANSWERvalue reported by manufacturer- stated as a
percent of full scale operating range`

experiment, based on RSS method
Total uncertainty - ANSWERfunction of sensitivity index
uncertainty analysis (results) - ANSWERindentify, quantify, and combine errors to
report uncertainty in results
uncertainty analysis (design) - ANSWERdetermine expected total measurement
