In general, the cross-sectional design technique requires one or more profile curves that describe the profile, or cross section, of the desired surface, and perhaps a trajectory curve that guides that way of … Synonyms for Cross-sectional design in Free Thesaurus. They are often used to measure the prevalence of health outcomes, understand determinants of health, and describe features of a population. Because these studies are essentially a “snapshot in time,” the most important concern with interpreting these studies is the inability to establish temporality, which leads to potential reverse causation.

Cross-sectional analysis is a type of analysis where an investor, analyst or portfolio manager compares a particular company to its industry peers. A cross-sequential design is a research method that combines both a longitudinal design and a cross-sectional design. Cross‐sectional studies serve many purposes, and the cross‐sectional design is the most relevant design when assessing the prevalence of disease, attitudes and knowledge among patients and health personnel, in validation studies comparing, for example, different measurement instruments, and in reliability studies. Unlike other types of observational studies, cross-sectional studies do not follow individuals up over time. Issues in the design of cross-sectional surveys. Cross-Sectional Study: A cross-sectional study is a research where the researcher analyses a particular context, group of people, or else a social phenomenon through a sample.

It should be adequate to accommodate all the cross-sectional elements of the highway and may reasonably provide for future development. The setting was a primary health centre catchment area in Goa, India. Hence, the two traditional research designs, longitudinal methods, which examine one group of people (such as people born in a given year), following and reexamining them at several points in time (such as in 2000, 2005, and 2010), and cross-sectional designs, which examine more than one group of people (of different ages) at one point in time. Choosing a representative sample. Enter the desired Power (80%) to detect a group difference at that confidence level. If the same study (same methodology and definitions) was conducted again in 2010, and later in 2015: How would this be useful? Reasons for doing a cross-sectional study • To assess the burden of disease in a population and to assess the need for health services.

In a cross-sectional survey, the risk factors and the outcome are measured simultaneously, and therefore it may be difficult to determine whether the exposure proceeded or followed the disease. Though design is a creative process it has economic consequences insofar as a product's shape, configuration and performance affect its marketability and its cost of production. A cross-sectional study is one of the observational studies that is also called as a prevalence study, or transverse study. Select the Two-sided confidence level of 95% from the drop-down list. The cross-sectional study is the most frequently used descriptive design in marketing research. Characteristics of Longitudinal Study and Cross-Sectional Study: Time duration: Longitudinal Study: A longitudinal study goes on for a longer period of time. Right of way (ROW) or land width is the width of land acquire for the road, along its alignment. The design of these surfaces fit into a special technique, the cross-sectional design. design the process of translating a product idea into a product which can be produced and marketed on a commercial basis. cross-sectional design research design in which several different participant age groups are studied at one particular point in time cross-sequential design research design in which participants are first studies by means of a cross-sectional design, but are also followed and assessed longitudinally +56 more terms Cross-sectional studies An “observational” design that surveys exposures and disease status at a single point in time (a cross-section of the population) Time Study only exists at this point in time 5.
