Answer #1

Measurement is usually defined as the assignment of numbers for objects in question

two students obtain different values for the same measured objects due to several reason

The most probable reason is that since it was merely measurement may be different units or values for same object are given hence the result will be different

Or it depends on what they are measuring. e.g in volumetric measurement it may be due to indeterminate error due to faulty grading of the burette or pipette

    Several groups of general chemistry lab students measured the equilibrium constant for the same chemical equilibrium. In comparing their results, they found that they had different values because the temperatures of the experiments were different. Everyone was disappointed by the inconsistency, except for Dexter when he realized the measurements were made at different measured temperatures: "My esteemed colleagues," he said, "together we have sufficient data to determine two additional thermodynamic parameters and show the lab instructor what we know!"
