Web1. You can know the mean more accurately than the data is known. If your data is rounded to one decimal, each item is uncertain by ± 0.05. The variance of the uniform distribution of total width 0.1 is 1 12 ⋅ 0.1 2. The variance of the sum of N items is then N 1200. The standard deviation of the mean is about 1 35 N. WebWith certainty we can say it is in the range of 6 to 7. Exactly where in that range is a estimate. We might guess it is 40% of the way, just less than halfway, between 6 and 7 or 6.4. If we had more marks on the scale we could make a better guess. It is clear that our estimate was close, but the measurement still does not align with a mark.
