Cross-sequential research combines the longitudinal and cross-sectional research methods.
A cross-sequential design is a method used in research that combines a longitudinal design as well as a cross-sectional design. This dual study is used to correct flaws that might be found in either of these designs alone. For instance, in sociology a cross-sectional study will study a group of people who have factors in common (age, gender, location, education, etc.) to determine how that effects some aspect of their lives in a short-term. A longitudinal study will study this
same group over a long term (years or even decades) to see how their lives are affected. Cross-sectional study is defined as an observational study where data is collected as a whole to study a population at a single point in time to examine the relationship between variables of interest.
What is Longitudinal Study?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 study can last from a few years to even decades depending on what kind of information needs to be obtained.
Differences between Cross-Sectional Study and Longitudinal StudyCross-sectional and longitudinal study both are types of observational study, where the participants are observed in their natural environment. There are no alteration or changes in the environment in which the participants exist. Despite this marked similarity, there are distinctive differences between both these forms of study. Let us analyze the differences between cross-sectional study and longitudinal study.
ConclusionIt is true, study design greatly depends on the nature of research questions. Whenever a researcher decides to collect data by deploying surveys to his/her participants, what matters the most are the survey questions that are placed tactfully, so as to gather meaningful insights. In other words, to know what kind of information a study should be able to collect is the first step in determining how to carry out the rest of the study. What steps need to be included and what can be given a pass. Continuing from the example above, a researcher wants to establish a relation between the variables, “jogging” and “cholesterol” in this case, one of the first things that a researcher would need to establish in this kind of study is, to tell the most about the relationship. A few questions to ask would be, whether to compare cholesterol levels among different populations of joggers, non-joggers at the same point in time? Or to measure cholesterol levels in a single population of daily joggers over an extended period of time? The first approach typically requires a cross-sectional study and the second approach requires a longitudinal study. What makes sequential research similar to longitudinal and crossSequential research designs include elements of both longitudinal and cross-sectional research designs. Similar to longitudinal designs, sequential research features participants who are followed over time; similar to cross-sectional designs, sequential research includes participants of different ages.
What is crossWith longitudinal, we look at one group over a long time. 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 crossa study in which two or more groups of individuals of different ages are directly compared over a period of time. It is thus a combination of a cross-sectional design and a longitudinal design.
What is the difference between a crossThe cross-sectional approach identified differences between cohorts of 252 users. The cross-sequential approach, on the other hand, allowed us to identify changes in individual users' user experience. These changes could also be tracked to different usage phases.
