Cross-sectional studies offer several advantages over other types of research design.

A. Cross-sectional A cross-sectional design (often in the form of a survey --literally, "overview") means that information is gathered on a sample (often fairly large) at one point in time. Therefore, a longitudinal study is more likely to suggest cause-and-effect relationships than a cross-sectional study by virtue of its scope. In general, the research should drive the design. But sometimes, the progression of the research helps determine which design is most appropriate.

We addressed this question using a detailed case study encompassing a rare suite of inter-connected cross-sectional and longitudinal investigations that have spanned the past two decades and included work on: (1) the decay and collapse of large-cavity forest trees (termed "trees with hollows"), (2) populations of a suite of species of arboreal marsupials that are reliant on trees with hollows... Cross-group friendships (the most effective form of direct contact) and extended contact (i.e., knowing ingroup members who have outgroup friends) constitute two of the most important means of improving outgroup attitudes. Using cross-sectional and longitudinal samples from different intergroup contexts, this research demonstrates that extended contact is most effective when individuals live

A research design is a set of logical procedures that (when followed) enables one to obtain evidence to determine the degree to which a theoretical hypothesis (or set of hypotheses) is/are correct. There are four basic types of research design: 1) case studies 2) cross-sectional designs 3) longitudinal designs 4) experimental designs. 2 CASE STUDIES Some Definitions According to Babbie(2001:G1 ORIGINAL INVESTIGATIONS The Uremic Dyslipidemia: A Cross-Sectional and Longitudinal Study M.M.

The choice among a longitudinal, mixed longitudinal, or cross-sectional design is often called for in educational and psychological research. The problem of choosing the most efficient design to estimate polynomial parameters for time-structured data is considered, and the comparison of the efficiencies shows that the assumed degree of the Marketing academics and practitioners frequently employ cross-sectional surveys. In recent years, editors, reviewers, and authors have expressed increasing concern about the validity of this approach.

For example, if you investigated changes in social behavior in 20-, 30-, and 40-yearolds all measured at one point in time, you would be conducting a cross-sectional research study. In other words, cross-sectional studies examine age differences, while longitudinal studies measure age changes.
