So that everyone will have the same initial sample, click on Calc – Set Base… and use 2003 as the base (seed) value. Collect random samples. Click on Calc – Random Data – Sample From Columns . Sample 25 rows from column c1, store in c3 and do it with replacement. This gives you a random sample of 25 numbers from c1 that are stored in c3.
