What is the Difference Between Longitudinal and Cross Sectional Study

Longitudinal studies and cross-sectional studies are two different types of research design. In a cross-sectional study you collect data from a population at a specific point in time; in a longitudinal study you repeatedly collect data from the same sample over an extended period of time.

What is the difference between a cross section and a longitudinal section?

Longitudinal studies differ from one-off, or cross-sectional, studies. The main difference is that cross-sectional studies interview a fresh sample of people each time they are carried out, whereas longitudinal studies follow the same sample of people over time.

What is the difference between longitudinal studies and cross-sectional studies quizlet?

The difference between cross-sectional and longitudinal research is that in cross-sectional research groups of people of one age are compared with a similar group of people of another age whereas in longitudinal research data is repeatedly collected on the same individuals at different stages of their aging and ...

Is cross-sectional or longitudinal better?

Cross-sectional studies can be done more quickly than longitudinal studies. That's why researchers might start with a cross-sectional study to first establish whether there are links or associations between certain variables. Then they would set up a longitudinal study to study cause and effect.

What are cross-sectional studies and longitudinal studies and why is it important to know which method was used?

Unlike longitudinal studies, which look at a group of people over an extended period, cross-sectional studies are used to describe what is happening at the present moment. This type of research is frequently used to determine the prevailing characteristics in a population at a certain point in time.

What is an example of cross-sectional study?

Another example of a cross-sectional study would be a medical study examining the prevalence of cancer amongst a defined population. The researcher can evaluate people of different ages, ethnicities, geographical locations, and social backgrounds.

What are the disadvantages of cross-sectional studies?

The weaknesses of cross-sectional studies include the inability to assess incidence, to study rare diseases, and to make a causal inference. Unlike studies starting from a series of patients, cross-sectional studies often need to select a sample of subjects from a large and heterogeneous study population.

What is the greatest drawback of the longitudinal method?

Longitudinal studies require enormous amounts of time and are often quite expensive. Because of this, these studies often have only a small group of subjects, which makes it difficult to apply the results to a larger population.

What is an example of longitudinal study?

What is an example of a longitudinal study? The 1970 British Cohort Study, which has collected data on the lives of 17,000 Brits since their births in 1970, is one well-known example of a longitudinal study.

Which is an advantage of longitudinal over cross sectional research?

Longitudinal and Cross-Sectional Studies: Advantages and Disadvantages. The key advantage to longitudinal studies is the ability to show the patterns of a variable over time. This is one powerful way in which we come to learn about cause-and-effect relationships.

Can a study be both cross sectional and longitudinal?

The simplest longitudinal descriptive study consists of two repeated cross-sectional studies on the same population or samples, looking for the same measurements. Yes - repeated cross-sectional analysis can be longitudinal as you are repeatedly measuring something.

Can a study be cross sectional and longitudinal?

A cross-sectional study is conducted at a given point in time. ... Cross-sectional study is conducted with different samples. Longitudinal study is conducted with the same sample over the years. Cross-sectional studies cannot pin down cause-and-effect relationship.

What is the main purpose of 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.
