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)


All the measurements that we do have errors. We cannot remove errors completely but reduce it.


There can be three main causes of errors in measurement:


Defect in instrument can lead to error in measurement. Different instruments can have little differences. So, they can cause errors.


Incorrect method of measurement: They may not have followed the correct methods of measurement like keeping eyes in straight line to the measuring point.


Use of different scales: They might have used different scales. So they could have different readings.
