Question

Two students measured the length of their desk, each using a different meter stick. One student reported a length of 18 cm and the other reported a length of 82 cm. What is the most likely explanation for the difference? A. One student read the meter stick incorrectly. B. The meter sticks were made from different materials. C. Each student read the meter stick from different angles. D. One of the meter sticks was improperly labeled due to a defect.

Answer 1

Since all the meter scales have same marking or scaling, thus it is not possible to have a defect in labelling of scale. Also the material of scale can't effect the labellind and thus measurement.

also, as the desk length is a linear measurement which does  not involve any angular point, thus student can't read from differnet angles.

Hence, the most likely reason for the difference in measurement is:

A. One student read the meter stick incorrectly
