(R-R) n(n-1) and it represents the likelihood of the discrepancy between the mean value R and the "true" value of R (assuming there are no systematic errors in the individual measurements of R). More specifically, there is a 67% probability that R will be within +S of the "true value" of R. In this formula, n represents the number of individual measurements made (5 in this case). As usual, the mean value R is given by S= = N 6 i=1 R=i=1 f= N Note that S is to be distinguished from the standard deviation o, N Ri i=1 n (R-R) n-1 which is a measure of the "scatter" or "spread" of the individual measurements R about their own mean value R. Note that S = defined as 1. Compute the mean value R of the measurements of the range R of the firings, and the standard deviation of the mean SR. Your experimental result for the range may now be stated as Rexp = R +S. 2. Compute the theoretical prediction R for the range using Eqn. (6). 3. Compare your Rexp = R +S with the predicted value R.
