Why is the cross-sectional method more common than the longitudinal method?
The results are obtained relatively quickly and it is less expensive
.
What advantage does the cross-sectional design have over the longitudinal design?
A key advantage using cross-sequential designs is that
it allows researchers to examine multiple age groups in a short period of time, compared to longitudinal designs
. It also enables researchers to test for cohort effects, which is often not possible in a usual longitudinal design.
What is the difference between longitudinal and cross-sectional research?
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.
Which is an advantage of longitudinal over cross-sectional research quizlet?
A benefit of longitudinal studies is that
researchers can collect data on the same people over time
. b. Cross-sectional studies collect data of different groups of people at the same time.
What are the advantages of a longitudinal research over the cross-sectional research?
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.
What are the similarities and differences of a longitudinal and cross-sectional design?
| Longitudinal study Cross-sectional study | Observes the same group multiple times Observes different groups (a “cross-section”) in the population | Follows changes in participants over time Provides snapshot of society at a given point |
|---|
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.
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 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.
What are the three types of longitudinal research?
There are a range of different types of longitudinal studies:
cohort studies, panel studies, record linkage studies
. These studies may be either prospective or retrospective in nature.
What is a major disadvantage of cross-sectional research quizlet?
A disadvantage of cross-sectional research is that it
just tells researchers about differences, not true changes
. … Because researchers cannot directly manipulate age, there are other differences each age group might have besides just age.
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 are cross-sectional studies and longitudinal studies and why is it important to know which method was used quizlet?
Longitudinal studies are relatively simple to conduct. Cross-sectional studies cannot separate the effects of age and generation. A benefit of longitudinal studies is
that researchers can collect data on the same people over time
. Cross-sectional studies collect data of different groups of people at the same time.
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.
Which of the following is a main disadvantage of the cross-sectional design?
The disadvantages of cross-sectional study include:
Cannot be used to analyze behavior over a period to time
.
Does not help determine cause and effect
.
The timing of the snapshot is not guaranteed to be representative
.
Which is the best description of the cross-sectional method of research?
A cross-sectional study is a
type of research design in which you collect data from many different individuals at a single point in time
. In cross-sectional research, you observe variables without influencing them.
