Thanks for writing. If your goal is to use the bootstrap to estimate the standard error of a statistic, you should generate B bootstrap samples, compute B statistics, then takes the standard deviation (not standard error) of those statistics. To be completely correct, you should use DF=N for the STD computation, but in practice the difference between dividing Sum(x[i]-xBar) by B or (B-1) is small.
