Random sampling and systematic sampling

WebbISA 530 recognises that there are many methods of selecting a sample, but it considers five principal methods of audit sampling as follows: random selection systematic selection monetary unit sampling haphazard selection, and block selection. Random selection Webbrandom sampling is one. Simple random sampling is defined as follows: 1. A statistical population is defined that consists of N sampling units; 2. n. units are selected from the possible samples in such a way that every unit has an . equal. chance of being chosen. The usual way of achieving simple random sampling is that each possible sample unit
