A longitudinal study, like a cross-sectional one, is observational so, once again, researchers do not interfere with their subjects however, in a longitudinal study, researchers conduct several observations of the same subjects over a period of time, sometimes lasting many years. For example, developmental research would be an ideal choice to assess the differences in academic and social development in low-income versus high-income neighborhoods it is most common when working with children as subjects for obvious reasons and can be undertaken using several methods: longitudinal, cross sectional, and cross sequential.

To draw inferences from cross-sectional research is affected by factors such as how time is measured, the type of developmental trajectory of the developmental process (ie, fixed longitudinal and cross-sectional designs 7.

Longitudinal studies have an obvious advantage over cross-sectional ones in providing information describing processes over time but often this advantage comes at heavy cost in both time and money. Cross-sectional designs occur in all areas of medical research, from preclinical, to clinical to epidemiological studies, although surveys, which are one type of such design, are most common in epidemiological studies. Start studying cross-sectional, longitudinal, sequential research learn vocabulary, terms, and more with flashcards, games, and other study tools.

The longitudinal study uses time as the main variable, and tries to make an in depth study of how a small sample changes and fluctuates over time a cross sectional study, on the other hand, takes a snapshot of a population at a certain time, allowing conclusions about phenomena across a wide population to be drawn. Among those design, there are five design are prominent, which are experimental and related, cross-sectional, longitudinal, case study and comparative research every design is particularly focused in terms of the research finding. Nonetheless, cross-sectional studies require less time to be set up, and may be considered for preliminary evaluations of association prior to embarking on cumbersome longitudinal-type studies longitudinal study designs.
