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 difference in their measurements? (Mention any three)

Answer 1

Hint: Some of the reasons for difference in their measurement could be:
1. Different measuring devices were used.
2. The smallest length that could be measured by different devices maybe different.
3. Measurement may not be along the shortest length in all three cases.
4. The end of the corridor may not be easily accessible.
5. The measuring devices may be faulty (not standardised)
6. Any other correct reason. (Any three can be considered)
