- The length of a metal block is measured 4 times using a ruler. The results are shown below: measurement # length l (mm) 1 23.5 2 23.8 3 23.2 4 23.6 First, calculate the mean length and fill it in the blank below. Next, fill in the blanks for the differences and in the table above. Finally, calculate the standard deviation, the standard deviation of the mean and the 2σ uncertainty and fill in the blanks below. Important notes (read before entering your answers): Enter the values in mm using decimal notation (e.g. 0.0123). A leading zero before the decimal point must be entered (e.g. 0.0123, not .0123). Do not use scientific notation, as it will not be recognized, and do not enter the units. Do not round the numbers, as this may cause rounding errors to accumulate.
