What is a cross section of a rectangle?

A cross section is the intersection of a plane and a three dimensional figure. A rectangular prism can have several different types of cross sections. If the cross section is perpendicular to the base, it will be the same as the lateral faces (for a rectangular prism).

What is difference between area and cross sectional area?

Answer. Area is somewhat that is occupied by an object when it is resting on asurface i.e area is the space which isused by the object. Whereas cross-sectional area is an area which we obtain when the same object is cut into two pieces. The area of that perticular cross section is know ascross sectional area.

Why do a cross sectional study?

Cross-sectional studies are used to assess the burden of disease or health needs of a population and are particularly useful in informing the planning and allocation of health resources. A cross-sectional survey may be purely descriptive and used to assess the burden of a particular disease in a defined population.

What is the limitation of cross sectional study?

However, it is important to be aware of the predictive limitations of cross-sectional studies: “the primary limitation of the cross-sectional study design is that because the exposure and outcome are simultaneously assessed, there is generally no evidence of a temporal relationship between exposure and outcome.”

What is the problem with cross sectional research?

Non-response is a particular problem affecting cross-sectional studies and can result in bias of the measures of outcome. This is a particular problem when the characteristics of non-responders differ from responders. Recall bias can occur if the study asks participants about past exposures.

What are the 3 major types of epidemiologic studies?

Three major types of epidemiologic studies are cohort, case-control, and cross-sectional studies (study designs are discussed in more detail in IOM, 2000). A cohort, or longitudinal, study follows a defined group over time.

How do you identify a cohort study?

In a cohort study, an outcome or disease-free study population is first identified by the exposure or event of interest and followed in time until the disease or outcome of interest occurs (Figure 3A).
