A cross-sequential design is a research method that combines both a longitudinal design and a cross-sectional design. The cross-sectional study design looks for associations at a certain time point. To prevent ribbon development along highways, control lines and building lines may be provided. 1. Choosing a representative sample.

Choosing a representative sample A cross-sectional study should be representative of the whole of the population, if the findings are to have external validity. Often these studies are the only practicable method of studying various problems, for example, studies of aetiology, instances where a randomised controlled trial might be unethical, or if the condition to be studied is rare.

It should be adequate to accommodate all the cross-sectional elements of the highway and may reasonably provide for future development. 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. If the same study (same methodology and definitions) was conducted again in 2010, and later in 2015: How would this be useful? They may be either single cross-sectional (Figure 3.1). 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. Enter the proportion of unexposed vs. exposed of 1.5. Unlike other types of observational studies, cross-sectional studies do not follow individuals up over time.
