SAMPLING TECHNIQUES INTRODUCTION
... sample of n=20. To use systematic sampling, the population must be listed in a random order. The sampling fraction would be n/N = 20/100 = 20%. In this case, the interval size, k, is equal to N/n = 100/20 = 5. Now, select a random integer from 1 to 5. In our example, imagine that you chose 4. Now, t ...

The Success/Failure condition is easily met, and the probabilities are quite close. It is important to note, however, that when the Succe ...
