Significant measurement meaning
WebSignificant digits from common measurements. Mass – analytical balances generally give many significant digits, particularly when weighing 0.1 g or more, you get 4, 5, or 6 significant digits. For example, 0.5012 g of a substance has 4 significant digits. Higher masses give you more significant digits until you reach the capacity of the balance. It is recommended for a measurement result to include the measurement uncertainty such as , where xbest and σx are the best estimate and uncertainty in the measurement respectively. xbest can be the average of measured values and σx can be the standard deviation or a multiple of the measurement deviation. The rules to write are: • σx has only one or two significant figures as more precise uncertainty has no meaning.
