The accuracy of an experimental value depends on the accuracy of all indirect measurements in the experiment, the numerical data in the formula used for the calculation, and the format of all direct measurements involved in calculating the desired value.
Объяснение
## Step 1The accuracy of an experimental value is determined by the precision of the measurements and calculations involved in the experiment. This includes the accuracy of all indirect measurements, the numerical data in the formula used for the calculation, and the format of all direct measurements involved in calculating the desired value.## Step 2The statement that an experimental result is always rounded freely, at the will of the experimenter, is not accurate. While it is true that the experimenter has some discretion in rounding, this is typically done to reflect the precision of the measurements and calculations, not at the experimenter's will.## Step 3The rounding of experimental results is usually done to reflect the precision of the measurements and calculations. This is done to ensure that the results are as accurate as possible, and to avoid overestimating the precision of the results.
