Introduction to Sampling Theory
... A systematic sample is generated by choosing every nth item in a list of the population until the required sample size has been reached. A systematic sample of houses in a metropolitan area could be obtained by choosing every 100th house in a list of all houses obtained from an assessment authority. ...

Sampling (statistics)
In statistics, quality assurance, and survey methodology, sampling is concerned with the selection of a subset of individuals from within a statistical population to estimate characteristics of the whole population. Each observation measures one or more properties (such as weight, location, color) of observable bodies distinguished as independent objects or individuals. In survey sampling, weights can be applied to the data to adjust for the sample design, particularly stratified sampling. Results from probability theory and statistical theory are employed to guide practice. In business and medical research, sampling is widely used for gathering information about a population .The sampling process comprises several stages: Defining the population of concern Specifying a sampling frame, a set of items or events possible to measure Specifying a sampling method for selecting items or events from the frame Determining the sample size Implementing the sampling plan Sampling and data collecting Data which can be selected↑ ↑
