why does every human measurement have uncertainty associated with it? Why must we manage the uncertainty during calculations?

because there are many numbers of the human measurement . we must manage the uncertainly doing calculations because we can know what we are calculating.

The uncertainity associated with human measurement is caused due to systematic and random error. Hence, managing these uncertainty during calculation is necessary to achieve a reasonable degree of accuracy.

Systematic errors are associated with the uncertainity introduced into our measurement due to the limitation of the measuring instrument which is employed or used during the experiment.

Radom error is usually due to the mistakes or uncertainty introduced by the experimenter. These could be associated with the level of expertise, understanding or technique employed.

Due to the importance associated with measurements or experiment, it is essential that a reasonable degree of accuracy is attained. Hence, the need to adequately manage uncertainity during calculations.
