A main advantage of a cross-sectional design is that it allows researchers to gather information about different age groups in a short period of time. They also offer great ways to discover and document age-related differences associated with certain behaviors.
What is good about cross-sectional study?
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.
What are the advantages of using a cross-sectional research study quizlet?
– The advantage of cross-sectional studies is that it can compare different population groups at a single point in time. This means it allows researchers to compare many different variables at the same time.
What are advantages and disadvantages of cross-sectional and longitudinal designs?
Longitudinal study is conducted with the same sample over the years. Cross-sectional studies cannot pin down cause-and-effect relationship. Longitudinal study can justify cause-and-effect relationship. Multiple variables can be studied at a single point in time.
What are the strengths and weaknesses of cross sequential study?
Strengths & Weakness of Sequential Study
- Strength: Mitigated Cultural Variations. By consistently studying the same group of people, researchers are able to eliminate cultural or demographic factors from their findings. …
- Weakness: Participant “Mortality” …
- Strength: Observing Changes. …
- Weakness: Poor Causational Analysis.
What is the purpose of cross-sectional studies quizlet?
compares the prevalence of a disease between exposed and unexposed groups.
Is a cross-sectional study reliable?
Under certain circumstances a cross-sectional design may still be a valid design when studying potentially causal associations. For example, if the exposure is assumed to be stable over time, a cross-sectional design may be valid.
Which of the following best describes the cross-sectional study design?
Which of the following best describes a cross-sectional design? Researchers recruit three groups: first graders, second graders, and third graders, and each participant participates in one session of an experiment.. … take more than one observation whereas cross-sectional studies usually take only measurements once.
Why is a cross-sectional study a limitation?
The primary limitation of cross-sectional studies is that the temporal link between the outcome and the exposure cannot be determined because both are examined at the same time. … With a cross-sectional study, it is impossible to determine whether the inability to reproduce exacerbates the stereotypies or the contrary.
What is one strength of the cross-sectional design?
One of the advantages of cross-sectional studies is that since data is collected all at once, it’s less likely that participants will quit the study before data is fully collected.
Which of the following are some strengths of a cross sectional study design?
Strengths and weaknesses of cross-sectional studies Relatively quick and easy to conduct (no long periods of follow-up). Data on all variables is only collected once. Able to measure prevalence for all factors under investigation. Multiple outcomes and exposures can be studied.
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.
What is the advantage of the cross-sectional approach over longitudinal?
The benefit of a cross-sectional study design is that it allows researchers to compare many different variables at the same time. We could, for example, look at age, gender, income and educational level in relation to walking and cholesterol levels, with little or no additional cost.
What is the major advantage of using a longitudinal research design vs a cross-sectional design?
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.
What are the advantages and disadvantages of a longitudinal study?
What are the pros and cons of a longitudinal study? Longitudinal studies are better to establish the correct sequence of events, identify changes over time, and provide insight into cause-and-effect relationships, but they also tend to be more expensive and time-consuming than other types of studies.
What is the difference between cross-sectional and sequential?
With cross-sectional, we look at a whole bunch of groups right now. With sequential, we look at a whole bunch of groups over time.
What is the difference between cross-sectional and longitudinal studies?
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 a cross-sectional model?
Cross-Sectional Multi-Factor Model Cross-sectional models estimate stock returns from a set of variables that are specific to each company, rather than through factors that are common across all stocks. Cross-sectional models use stock-specific factors that are based on fundamental and technical data.
What are the advantages and disadvantages of cross sectional studies?
Advantages/Disadvantages of Cross-Sectional Study
|Cheap and quick||Useless for determining cause and effect|
|Multiple variables at the time of a data snapshot||Snapshot timing may not be representative|
|Data works for various types of research||Flawed if there is a conflict of interest|
What is a cross sectional study quizlet statistics?
Cross-sectional studies are observational studies that collect information about individuals at a specific point in time or over a very short period of time. … For the lung cancer study, it could be that individuals develop cancer after the data are collected, so the study will not give the full picture.
Which of the following are characteristics of cross sectional research studies?
Cross-sectional research involves using different groups of people who differ in the variable of interest but share other characteristics, such as socioeconomic status, educational background, and ethnicity. Cross-sectional research studies are often used by researchers studying developmental psychology.
What is the problem with cross-sectional research?
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 a good sample size for a cross-sectional study?
A smaller ‘d’ implies a larger sample size. Therefore, the choice of ‘p’ is crucial. = 400 this sample size will enable us to detect the truth if the prevalence is between 18-22% (or more). = 1900 this sample size will enable us to detect the truth if the prevalence is between 4-6% (or more).
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 analytical cross-sectional study?
In analytical cross-sectional studies, data on the prevalence of both exposure and a health outcome are obtained for the purpose of comparing health outcome differences between exposed and unexposed. Analytical studies attempt to describe. the prevalence of, for example, disease or non-disease by first.
What type of study is a cross-sectional study?
Cross-sectional study design is a type of observational study design. In a cross-sectional study, the investigator measures the outcome and the exposures in the study participants at the same time.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
