Expenm 1. Why should weighing data or any other measurement data be recorded immediately in Measurement and Density your laboratory manual and not on a scrap of paper? 2. An object was carefully weighed five times on a multiple-beam balance. The balance was zeroed each time. The masses were: 11.36 g; 11.37 g; 11.40 g; 11.38 g; and 11.39 g. Calculate the average value of these measurements. (Please show all work.) a. average b. Calculate the standard deviation, s.d., of this set of measurements using the range of the data and the square root of the number of measurements averaged. (Please show all work.) s.d. =
