The Method of file organisation in which data records in a file are arranged in a specified order according to a key field is known as the Sequential method.
A cross-sequential design is a research method that combines both a longitudinal design and a cross-sectional design. It aims to correct for some of the problems inherent in the cross-sectional and longitudinal designs.
The sequential method is used to allocate the cost of service departments to other departments within an organization. Under this approach, the cost of each service department is allocated one department at a time. Thus, the cost of one service department is allocated out to all user departments, which may include other service departments. Once these costs have been allocated, the costs of the next service department are allocated. The first department cannot receive an allocation from any other departments - in essence, there is a one-way cost allocation.
Sequential sampling is a non-probability sampling technique wherein the researcher picks a single or a group of subjects in a given time interval, conducts his study, analyzes the results then picks another group of subjects if needed and so on.
