Readers ask: What is a weakness of a longitudinal study?

There are, of course, drawbacks to longitudinal studies, panel attrition being one of them. Another weakness is that while longitudinal data is being collected at multiple points, those observation periods are pre-determined and cannot take into account whatever has happened in between those touch points.

What are some advantages and disadvantages of longitudinal studies?

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 is most likely the biggest problem with longitudinal research?

The biggest problem in longitudinal research comes from changing historical context. Seeks to understand how and why people of all ages and circumstances change or remain the same over time. a time when a certain type of development is most likely, although it may still happen later.

What is one of the major drawbacks of the longitudinal method?

Another huge drawback to any longitudinal study is the great amount of time it needs to collect all the data that is needed. Usually, it takes a long period of time to gather results before you can start making patterns.

What are the advantages and disadvantages of a cross-sectional versus a longitudinal study design?

Longitudinal study is conducted with the same sample over the years. Cross-sectional studies cannot pin down cause-and-effect relationship. Longitudinal study can justify cause-and-effect relationship. Multiple variables can be studied at a single point in time.

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.

Which of the following is a disadvantage associated with longitudinal research?

Disadvantages of longitudinal studies are associated with the length of time it takes to conduct the research, the cost of sustaining the study over time, and the potential for participants to “drop out” in the course of the study (research mortality).

Which outcome is a disadvantage of a longitudinal research design?

Research time The main disadvantage of longitudinal surveys is that long-term research is more likely to give unpredictable results. For example, if the same person is not found to update the study, the research cannot be carried out.

What is a longitudinal study example?

Longitudinal research is occasionally used to study unique individual cases. Longitudinal case studies are studies that gather copious amounts of data on a single person or small group of people. For example, a five-year study of children learning to read would be a cohort longitudinal study.

Why are longitudinal studies good?

The benefit of a longitudinal study is that researchers are able to detect developments or changes in the characteristics of the target population at both the group and the individual level. The key here is that longitudinal studies extend beyond a single moment in time.

Which is a major problem with longitudinal designs?

The main challenge of using a longitudinal design is the cost in time and resources. These studies are much more expensive and take much longer to conduct than a cross-sectional study with the same number of participants. A second issue is the impact of repeated testing.

What are some of the drawbacks to the case study method?

Disadvantage of Case Study Method of Data Collection

  • Limited Representatives. Due to as narrow focuses a case study has limited representatives and generalization is impossible.
  • No Classification.
  • Possibility of Errors.
  • Subjective Method.
  • No Easy and Simple.
  • Bias Can Occur.
  • No Fixed Limits.
  • Costly and Time Consuming.

What would be the greatest methodological limitation of a longitudinal design?

What would be the greatest methodological limitation of a longitudinal design? (See pp. 52-56 in the book.) – the loss of participants over time due to death, relocation, divorce, etc.

What is one advantage of a cross-sectional study over a longitudinal study?

A key advantage using cross-sequential designs is that it allows researchers to examine multiple age groups in a short period of time, compared to longitudinal designs. It also enables researchers to test for cohort effects, which is often not possible in a usual longitudinal design.

Why is a cross-sectional study a limitation?

The primary limitation of cross-sectional studies is that the temporal link between the outcome and the exposure cannot be determined because both are examined at the same time. With a cross-sectional study, it is impossible to determine whether the inability to reproduce exacerbates the stereotypies or the contrary.

What are differences between a longitudinal and cross-sectional studies?

Longitudinal studies differ from one-off, or cross-sectional, studies. 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.
