Option d) both a and b
- The new measured value of mass is substantially different from their previous value, however this number is more accurate than their previous finding because the uncertainty is reduced.
- The precision of a substance is defined as the degree to which two or more measurements agree with one another. It is incredibly precise but not always accurate to measure something if you weigh it five times and get 3.2 kg each time. Accuracy is not necessary for precision.
- The rounding of a calculated value reflects the degree of uncertainty associated with the values utilised in the calculation. Measured values may be precise or accurate (near to the true value) (showing little variation when measured repeatedly).
- The level of measurement uncertainty affects a measuring system's accuracy and precision. The degree to which your measured data depart from an average or predicted value is measured quantitatively as uncertainty.
