The use of random numbers, an alternative method also involves numbering of population members from 1 to N. Then, the sample size of n has to be determined by selecting numbers randomly. The necessity to have a large sample size can be a major disadvantage in practical levels. Random is a term used in mathematics (and less formally) to mean that there is no way to reliably predict an outcome (to know what will happen before it happens) or sense a pattern. A random sample is defined as a sample where each individual member of the population has a known, non-zero chance of being selected as part of the sample.
