Straight to the point:

What are the advantages and disadvantages of SYSTEMATIC and RANDOM sampling???

advt of systematic sampling: easy to keep track of what u have sampled
this method avoids bunching and is simple and easy to apply

random sampling is advantageous as it allows a fair test to be carried out;it is not biased
