A longitudinal study and a cross-sectional study are methods of collecting scientific data. A longitudinal study is the method that gathers data on a subject for a particular period of time and the subject's response to particular variables. A cross-sectional study is where more than one subject is used for the collection of data at different points in time in response to particular variables. These types of studies are sometimes used to determine correlation.
In a longitudinal study, the researcher collects data by taking a longer study period. whereas in the cross-sectional study the researcher collects data at a point in time (within a short period of time)
A longitudinal cohort study involves studying a specific group of people over an extended period of time.
A longitudinal study is a study that goes on for a long time. An example of this method of research would be an ethnography.
in psychology terms what is a naturalistic experiment and a longitudinal study?
The three main types of longitudinal studies are cohort studies, panel studies, and trend studies. Cohort studies follow a specific group of individuals over time, panel studies revisit the same group of individuals at multiple points, and trend studies analyze data collected from different samples at various time points.
A potential bias of the longitudinal Dunedin Multidisciplinary Health and Development Study, conducted in 1972-1973, lies with:
cross-sectional
You cant see how behaviours or results change over time. Cant gather a wealth of data of longitudinal studies. Basically the advantages of a longitudinal study is the disadvantages of snap shot studies.
longitudinal design
so youll know witch way the world is going
8 variables and 25 observations

a longitudinal study and its topic is critiqued for quite a lenghty period of time. this study is undertaken by the researcher and lasts for years, so in saying this it is quite obvious that this is a study that is taken into the future. however, a cross sectional study critiques its research at something that has happened or occured at a specific point in time. it may be a person's experience or an event of some interest.
