The Mathematical Effects of Random Measurement Errors

[ii] Enter the formula “=AVERAGE(A1:A12)” into a free cell, getting 274.0816. [iii] Enter the formula “=STDEV(A1:A12)” into another free cell, getting 5.692778. [iv] Round the standard deviation to 5.7, which is two significant digits. [v] Round the average to 274.1, the same precision as the rounded standard deviation ................
