q. with suitable example differentiate between accuracy and precision. sol. accuracy accuracy is the closeness with which instrument reading
q. with suitable examples differentiate between limiting and known errors.sol. limiting errors guarantee errors the accuracy and precision of an
reproducibility and repeatability are measures of closeness with which a given input may be measured over again. the two terms cause confusion.
if the instruments has no drift it is perfectly reproducible. no drift means that with a given input the measured values do not vary with time.drift
