      A faster and less cumbersome method is to use a . random number table. You worked with ways of getting random numbers in the previous lab. You can use the numbers in the table to select sampling positions (e.g. paces along a trail, GIS coordinates, termite holes in a wall that you have numbered etc.).

      In order to avoid biased samples, we need to make sure the sampling method is equitable and that there is a known probability for each member of the population to be selected. While the principle of simple random sampling is probably clear, it is by no means simple to implement. One approach is to use a computer-generated table of random digits.

      Simple random sampling is a more trustworthy method, but it is usually less convenient. Cluster Sampling – The random selection of clusters (groups of population member) rather than individual population members. Cluster Sampling: A method for drawing a sample from a population in two or more stages.

      AU Section 350-Audit Sampling: Attribute Sampling. Attribute sampling is a statistical approach used with tests of controls. It requires the use of a probabilistic sample selection method (random or systematic sampling). Attribute sampling allows the auditor to estimate the proportion of population items containing a specified characteristic.
