Longitudinal Study And Cross Sectional Study
Cross sectional studies can be done more quickly than longitudinal studies.
Longitudinal study and cross sectional study. That s why researchers might start with a cross sectional study to first establish whether there are links or associations between certain variables. While longitudinal studies repeatedly observe the same participants over a period of time cross sectional studies examine different samples or a cross section of the population at one point in time. A longitudinal study requires a researcher to revisit participants of the study at proper intervals.
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. Longitudinal studies and cross sectional studies are two different types of research design. For the first 1 type of requirement cross sectional study can be used while longitudinal study can be used to study the second 2 type of inquiry.
Cross sectional study is conducted with different samples. There are also cross sectional designs defined as sampled. Longitudinal study is conducted with the same sample over the years.
Here are the list of 21 major differences between cross sectional study and longitudinal study. In a cross sectional study you collect data from a population at a specific point in time. A longitudinal study is an observational study that involves repeatedly examining the same subjects to detect changes that may occur over a period of time while a cross sectional study is a type of observational study that involves collecting data from many different individuals at a specific point in time.
A longitudinal study is a research study in which the research continues for a longer period and uses the same sample at each phase. Cross sectional studies cannot pin down cause and effect relationship.

Longitudinal vs cross sectional studies the opposite of a longitudinal study is a cross sectional study. A cross sectional study the not so distant cousin to longitudinal is intended to compare multiple population groups at a single point in time. A cross sectional study is a one contact program with the target population having the outcome but the longitudinal study needs a constant follow up with the sample.
