The factors might include:

  • faulty measuring tool or instrument
  • random error by the students
  • not accounting for temperature changes

What is Error in measurement?

Error in Measurement can be defined as difference in value between the actual value and the measured value.

There are some factors that might have contribute to the inaccuracy in the measurement of the metal block and they include :

  • faulty measuring tool or instrument

The students may have have used a faulty instrument or an inaccurate instrument. The accuracy of the measurement will depend on the kind of scale they used. A kitchen scale, for example, is probably less accurate than a calibrated scale in a chemistry lab.

  • random error by the students

Random errors occurs when there might have been an error due to inability to read the accurate value of the instrument.

  • not accounting for temperature changes

Density varies with temperature and their might have been slight changes in temperature leading to inaccuracy in the readings.

In conclusion, errors can be mitigated by taking into account when we make a measurement by reporting an uncertainty value.
