Does not permit inferences about cause-and-effect relationships. Permits inferences about cause and effect relationships.
Findings may not generalize for the real world
. Age-related changes may be distorted because of biased sampling, selective attrition, practice effects, and cohort effects.
What is one problem with longitudinal research quizlet?
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. based on observations, repeated experiences, verifiable experiments; not theoretical.
Which 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 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.
Why are longitudinal studies bad?
1. They
require huge amounts of time
. Time is definitely a huge disadvantage to any longitudinal study, as it typically takes a substantial amount of time to collect all the data that is required. Also, it takes equally long periods to gather results before the patterns can even start to be made.
What qualifies as a longitudinal study?
A longitudinal study, like a cross-sectional one, is
observational
. So, once again, researchers do not interfere with their subjects. However, in a longitudinal study, researchers conduct several observations of the same subjects over a period of time, sometimes lasting many years.
What are the three types of longitudinal studies?
There are a range of different types of longitudinal studies:
cohort studies, panel studies, record linkage studies
. These studies may be either prospective or retrospective in nature.
What is a disadvantage of longitudinal research?
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.
Which is a major problem with longitudinal designs?
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 the drawback or disadvantage of longitudinal research?
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 are two primary disadvantages of conducting longitudinal studies?
They require enormous amounts of time. 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 is an example of a longitudinal research study?
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.
Are longitudinal studies more reliable?
Longitudinal data collection allows researchers to build up a
more accurate and reliably
ordered account of the key events and experiences in study participants’ lives. Understanding the order in which events occur is important in assessing causation.
Why do people drop out of longitudinal studies?
Dropout in longitudinal surveys has three separate sources:
failure to locate research participants, failure to contact participants
, and failure to achieve cooperation.
Do longitudinal studies eliminate cohort effects?
increases in cognitive scores at different ages, which were accompanied by nearly constant cross-sectional age differences, but positively inflated estimates of longitudinal age differences.” Thus, he showed that
longitudinal studies are not 4 Cohort Effects
Page 5 immune to secular changes in performance and in some …
Which of the following is an advantage of a longitudinal study?
The key advantage to longitudinal studies is
the ability to show the patterns of a variable over time
. This is one powerful way in which we come to learn about cause-and-effect relationships.
