Record your value in data table 1 as length. make 4 other measurements for length at different places and record them. you want to get a good representation for the variations of the block's length. calculate the average value of the length. determine the delta^2=(average - measured)^2 for each measurement. use equation [2] to calculate the standard deviation of length and record its value in the data table calculate the total uncertainly using equation[3]; use the caliper's uncertainty and the standard deviation for the length measurement. record the average and total uncertainly of the length on the data sheet: length =average+delta total(units). s. d. =squareroot delta^2/n-1 delta_total = squareroot delta^2_caliper + delta ^2_s. d repeat steps i - 5 for the height (the shortest side) and width (the remaining side) of the wooden block. record the average and its total uncertainty on the data sheet for height and width.
