Longitudinal Cross Sectional Study

The main difference between longitudinal and cross sectional study is that longitudinal studies look at variables repeatedly over a period of time while cross sectional studies look at variables at a particular point in time.
Longitudinal cross sectional study. Instead of collecting data over time on a single variable a cross section is framed allowing a researcher to see differences among population subsets in several categories. While longitudinal research involves collecting data over an extended period of time cross sectional research involves collecting data at a single point in time. Longitudinal design is a research study where a sample of the population is studied at intervals to examine the effects of development.
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. A cross sectional study the not so distant cousin to longitudinal is intended to compare multiple population groups at a single point in time. Both longitudinal studies and cross sectional studies are two types of observational studies.
So once again researchers do not interfere with their subjects. In a longitudinal study you repeatedly collect data from the same sample over an extended period of time. Longitudinal research is often contrasted with cross sectional research.
Longitudinal study like the cross sectional study is also an observational study in which data is gathered from the same sample repeatedly over an extended period of time. Longitudinal studies differ from one off or cross sectional studies. The key difference between the two studies stem from the fact that while a cross sectional study presents the researcher with a cross sectional analysis of the research a longitudinal study.
There are also cross sectional designs defined as sampled. Longitudinal study can last from a few years to even decades depending on what kind of information needs to be obtained. 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. Features of longitudinal vs cross sectional studies. In a longitudinal study you repeatedly collect data from the same sample over an extended period of time.
