A student calculates the density of a liquid five times and gets the results (all in g/cm ), 1.8, 2.0, 2.0, 1.9 and 1.8. What would you suggest as the best estimate and uncertainty based on his measurements? He is told that the accepted value is 1.85 g/cm3.
What is the discrepancy (between his best estimate and the accepted value)? Do you think it is significant? Note: Do NOT calculate an average and standard deviation for the given data - reason your way to the best estimate and uncertainty (range).
