Question

Three students measured the length of a corridor and reported their measurements. The values of their measurements were different. What could be the reason for the difference in their measurements?

Answer 1

Some of the reasons for the difference in their measurement could be:

1. Different measuring devices were used.
2. The smallest length that could be measured by different devices may be different.
3. The measurement may not be along the shortest length in all the three cases.
4. The end of the corridor may not be easily accessible.
5. The measuring devices may be faulty (not standardized).
