What factor is a problem with longitudinal research?
Longitudinal studies require enormous amounts of time and are often quite expensive. Because of this, these studies often have only a small group of subjects, which makes it difficult to apply the results to a larger population.
What are the limitations of longitudinal studies?
List of Disadvantages of Longitudinal Studies
- They require huge amounts of time.
- They risk gathering data that is not 100% reliable.
- They would risk experiencing panel attrition.
- They require a large sample size.
- They can be more expensive compared with cross-sectional studies.
What is an example of longitudinal study in psychology?
For example, a five-year study of children learning to read would be a cohort longitudinal study. Researchers might compare environmental and other factors in the children and measure outcomes over time. Some longitudinal studies are retrospective in nature; these examine data and evidence after the fact.
How does confounding variables affect the validity of the study?
Confounding variables are common in research and can affect the outcome of your study. This is because the external influence from the confounding variable or third factor can ruin your research outcome and produce useless results by suggesting a non-existent connection between variables.
What is problem with longitudinal research?
However, the longitudinal survey also has significant problems, notably in confounding aging and period effects, delayed results, achieving continuity in funding and research direction, and cumulative attrition.
What is an example of longitudinal research study?
What is an example of a longitudinal study? The 1970 British Cohort Study, which has collected data on the lives of 17,000 Brits since their births in 1970, is one well-known example of a longitudinal study.
What are confounding factors in a study?
A confounding variable (confounder) is a factor other than the one being studied that is associated both with the disease (dependent variable) and with the factor being studied (independent variable). A confounding variable may distort or mask the effects of another variable on the disease in question.
What are confounding factors in an experiment?
A confounding variable is an “extra” variable that you didn’t account for. They can ruin an experiment and give you useless results. They are like extra independent variables that are having a hidden effect on your dependent variables. Confounding variables can cause two major problems: Increase variance.
What are some advantages and disadvantages of longitudinal research?
What are the pros and cons of a longitudinal study? Longitudinal studies are better to establish the correct sequence of events, identify changes over time, and provide insight into cause-and-effect relationships, but they also tend to be more expensive and time-consuming than other types of studies.
What are two primary disadvantages of conducting longitudinal studies?
Longitudinal studies are a method of observational research. The primary disadvantage of using longitudinal studies for research is that long-term research increases the chances of unpredictable outcomes. If the same people cannot be found for a study update, then the research ceases.
