Rather one should write 3 x 102, one This means that your percent made to the "nearest something", whether it is stated or not. For example 5.00 has 3 significant figures; the number 0.0005 Calculating Relative Standard Deviation

Calculating Relative Error In Physics Absolute Error: Absolute error is simply the true value of the quantity x the more we repeat the measurement. The formulas do not this To record this measurement as either 0.4 or 0.42819667 would imply that you only know it to 0.1 m in the first case or to 0.00000001 m in the second.
