Right Answer is: C

SOLUTION

Resolution:

  • The resolution of a measurement system is the smallest yet to distinguish differences in values.
  • The specified resolution of an instrument has no relation to the accuracy of the measurement.

Accuracy:

  • The error between the real and measured value.
  • Accuracy is an inidication of the correctness of a measurement.

Precision:

  • The term precision is used to express the random measurement error.
  • The random nature of the deviations of the measured value is mostly of thermal origin.

Deviation:

The difference between the value of an observation and the mean of the bulk in mathematics & statistics is termed as Deviation.
