Because to be this exact we would have to measure down to the size of the atom, and this isn't important/cost effective/practical in 99.999999% of the areas that we would use measurements in.
Almost every measurement is done by humans, and as we know, humans are far from infallible.

∙ 11y agoGood question. Suppose you had a line segment that was two inches long and you divided it into three equal portions. Dividing 2 by 3 on your calculator, you learn that each portion is 0.666 666 666 666 666 666 666 667 inches. Wow, that's pretty precise. But wait. When you measured the segment, did you obtain a reading of 2.000 000 000 000 000 000 000 000 000, or was it more like 2.0 inches? By mathematical operations we can generate figures of astonishing apparent precision, but they'd no more accurate than our least accurate measurement.

You can be precise and hit the 1 point multiple times, or you can be accurate and hit the bulls-eye over and over again.

∙ 12y agoBecause it is impossible to know exactly the measure of a quantity; statistical variations are absolutely unavoidable. A measurement is correct only if it is expressed with the calculated uncertainty.
Wiki User
∙ 7y agoThere are some measurements which maybe inexact because the characteristic which is being measured is continuous and so an exact measure is not possible. However, that is certainly NOT the case for measures such as the number of people in your class at a specific time or the number of pet dogs that you have. So the assertion in the question is rubbish.

∙ 15y agoProbably because your measurer doesn't know how to measure exactly.
