Length Measurements The lengths of three woodblocks is measured one at a time, in çentimeters and inches, and mecasurement values are recorded in the respective row and column in the Data Table 3. Then the ratios of the lengths in centimeters to inches is calculated by dividing cm values in the second column to the inch values in the third column, and values entered in the last ratio (cm/in) column. The mpan of the three ratios, which should be near the standard (2.54 cm/inch), is determined. Finally, the percent error of the measurements is calculated using the formulae given below. % Error =*/Standard value– observed mean/x 100 Standard value *absolute difference (no negative sign) able 3.
