Example: Suppose the outcomes of several repetitions of an experiment have been recorded as follows
12.3075 12.3351 11.9949 12.2722 12.3117 12.0766The four decimal places used to denote the results are meaningless, since the repeated measurements indicate that at most the first decimal place is valid (a closer analysis shows that the average of the result is 12.21, with a standard deviation of 0.14).
