A sample whose elements are selected by a chance process is referred to as a random sample 1 or probability sample 1. If a complete list of sampling units is available, this is called a sampling frame 3. In simple random sampling 4 a proportion of sampling units is selected from the frame at random 2. This proportion is called the sampling fraction 5 or sampling ratio 5. Systematic samples 6 are drawn systematically 7 from a frame in which the sampling units are consecutively numbered. The sample is selected by taking the nth, (n + s)th, (n + 2s)th, ..., etc. unit, where n is not larger than s and is selected at random. In cluster sampling 8 population elements are not drawn individually, but in groups which are called clusters 9 .
