Its most important application lies in the field of epidemiology and disease research. Comparison of data on a subject at a certain point in time. Design While conducting a cross-sectional research, the important points one needs to remember are: All jets and associated abilities can be more accurately defined in this manner.
Usually, it takes a long period of time to gather results before you can start making patterns. These can be the faculty not being supportive enough or the professors being too strict in their behavior towards the students.
Its nature and Course.
Understanding the Pros and Cons of Cross-sectional Research Cross-sectional research is used in different areas like psychology, business, epidemiology, etc. If you are only depending on the same group of subjects for a study that takes place once in a while for years, some of these subjects will obviously no longer be able to participate due to various reasons, such as refusal, changes in contact information and death, which cuts down useable data that can be drawn for an ultimate conclusion.
They have more power than cross-sectional studies. They drop out from a panel study. All the topics of longitudinal research are equals and hence they face the same outwardnesss doing them easy comparable with each other. By using the same subjects, scientists and research personnel can allow for a measurable change over a certain period of time to be collected.
The fact that all topics are susceptible to the same outwardnesss means that they have a alone environment and the features of their development may reflect merely that of their equals ; this is called the cohort consequence.
Because they are perfect for doing research on developmental trends, longitudinal studies can make observation of changes more accurate, making them a more preferred method in various fields.
But, longitudinal research also comes with many disadvantages. Information collected in one session could take old ages to roll up in a longitudinal survey.
While longitudinal data is collected at multiple points, these observation periods are pre-determined and cannot be taken into account no matter what happens between these points.
This means that bigger pools of topics are made available to the theoretician and his chosen topics should accurately reflect the population. And though people usually might not remember past events, it can be solved by means of actual recording, thus ensuring a high level of validity.
In medicine, such a method is used to discover indicators or predictors of certain illnesses, while in advertising, it is used to identify changes that an ad campaign has produced in the behaviors and attitudes of people belonging to the target audience who have seen the advertisement.
A longitudinal study is often used in psychology in studying developmental trends across life spans and in sociology in studying life events throughout generations or lifetimes.
They can show clear variable patterns over time. This disadvantage means that such studies should have a large number of subjects who are willing to cooperate. For illustration the consequence of twenty-four hours attentions as opposed to rear supervising of the kid.
EduZenith Staff Last Updated: One key advantage of performing longitudinal studies is their ability to show patterns of a variable over time, which is a very powerful way through which researchers come to learn about the relationships of cause and effect.
This is besides a major disadvantage of longitudinal attacks. They can be costly compared to cross-sectional studies. The information is collected through interviews.
Assessment of outcomes and risk factors for the entire population is also done with little trouble, as the sample is a near-perfect snapshot of the whole. In the longitudinal attack there is one survey group.
Participants may travel off. Low to Moderate Cost The ease of gathering the needed information translates to cost-effectiveness. The result of the research forms the basis of case studies and analysis.
Let us try to understand this with the help of an example. One of the common observations in the longitudinal method is that, people tend to show completely different behavior when they are being observed or under scrutiny.
Her expertise lies in travel and home-decorating. This can be categorized as a cross-sectional research, as you do not know what caused them to have an opinion, whether good or bad about the college. You visit a college and take the feedback of the faculty from a specific set of students.Radiology Methods Pros and Cons.

Advantages & Disadvantages of Cross-Sectional Studies By Natalie Andrews ; Updated June 28, A cross-sectional study, a type of descriptive, observational study, involves measuring different variables in the population of interest at a single point in time.
A cross sectional study design was used to investigate the extent of chronic fatigue and the associated psychosocial exposures in a developing country. The setting was a. Discuss the Pros and Cons of Cross-sectional and Longitudinal approaches to the study of development The study of development is that of changes in physical, cognitive, social and emotional capabilities over time.
The study is usually carried out on infants and children as their changes are faster and more dramatic than adults. There are some advantages of cross-sectional approach: 1. The usage of cross-sectional method to carry out quite extensive investigations for a short period.
2. It allows to cover various age categories and to reveal a lot of determinates. 3. Cross-sectional method gives the opportunity to retrace the dynamics of age development, succession of different phases and periods of formation of psyche.
4. The cross-sectional approach to research entails the study of two or more groups of similar ages. The groups are tested and their capabilities compared to evaluate development (the difference of skills).Download
