Abstract: |
This chapter introduces another sampling design: systematic sampling. The main advantage of this design is its simplicity and the ease with which it can be implemented by the researcher. Another benefit of the systematic sampling design is that the sample selected using this method will be uniformly distributed across the population—since, as will be shown later, the sampling units in systematic sampling are equally spaced. Even in simple random sampling (SRS), sample units may display clustering. This is not possible in systematic sampling. One disadvantage of systematic sampling is that it may interact with any underlying periodicity among the population units. Regarding the accuracy of the resulting estimators, the outcomes vary depending on the structure of the sampling frame in relation to the characteristic under study. Under certain population conditions, systematic sampling can be more efficient than simple random sampling, while in other cases, it may be less efficient. Furthermore, the outcome of the efficiency comparison with SRS may even change for the same population if a different sampling frame or ordering of population members is used. The specific implementation details, the practical advantages of the method, the properties of the estimators, and possible ways to improve systematic sampling are presented in the following paragraphs, where a detailed study of this sampling design is provided. This design, either used alone or in combination with another method, is one of the most commonly applied in practice.
