Results are typically used to understand the attitudes, beliefs, or knowledge of a particular group. Assuming that care has been taken in the development of the survey items and selection of the survey sample and that adequate response rates have been achieved, surveys results are
generalizable
.
Can surveys be generalized?
No.
Nothing can be generalized
. … However, in recent times statisticians are objecting generalisation of results for any population. They opine that the results for the sample can only be generalised for the sample only.
What makes a survey generalizable?
Very simply, generalizability is
a measure of how useful the results of a study are for a broader group of people or situations
. … If the results can only be applied to a very narrow population or in a very specific situation, the results have poor generalizability.
How do you know if a study is generalizable?
If
the results of a study are broadly applicable to many different types of people or situations
, the study is said to have good generalizability. If the results can only be applied to a very narrow population or in a very specific situation, the results have poor generalizability.
Are experiments generalizable?
Specifically, experimental findings from one population can be “re-processed”, or “re-calibrated” so as to circumvent population differences and produce valid generalizations in a second population, where experiments cannot be performed.
How do you know if a study is internally valid?
It is related to
how many confounding variables you have in your experiment
. If you run an experiment and avoid confounding variables, your internal validity is high; the more confounding you have, the lower your internal validity. In a perfect world, your experiment would have a high internal validity.
What is an example of a generalization?
Generalization, in psychology, the tendency to respond in the same way to different but similar stimuli. … For example, a
child who is scared by a man with a beard may fail to discriminate between bearded men and generalize
that all men with beards are to be feared.
What is a limitation that may affect the generalizability of research results?
What is the limitation that affects the generalizability of research results?
Small sample size
. Dr. Matter is interested in knowing more about brain injury to the occipital vortex, and he studies patients individually in order to gain in-depth knowledge about their behaviors.
What is the best way to ensure the results of a study are generalizable to a population?
The best way to ensure representativeness is
to sample randomly
However, since the nature of sampling in qualitative research is non-probabilistic, this type of generalization in qualitative research is a weak point.
How is doing a replication study useful?
When studies are replicated and achieve the same or similar results as the original study,
it gives greater validity to the findings
. If a researcher can replicate a study’s results, it means that it is more likely that those results can be generalized to the larger population.
What does it mean when a study Cannot be replicated by an independent researcher?
What does it mean when a study cannot be replicated by an independent researcher?
The replication was done incorrectly
.
Can lab experiments be Generalised to real life?
laboratory studies are good at telling whether or not some manipulation of an independent variable causes changes in the dependent variable, but many scholars assume that these
results do not generalize to the “real-world
.” The general concern is that, due to the ‘artificiality’ and ‘simplicity’ of the laboratory, some …
What is an example of a natural experiment?
For example, a woman may defer having a child if she gets a raise at work. …
The sex of the first two children
, then, constitutes a kind of natural experiment: it is as if an experimenter had randomly assigned some families to have two children and others to have three.
What improves internal validity?
Controls are required to assure internal validity (causality) of research designs, and can be accomplished in four ways: (1) manipulation, (2)
elimination
, (3) inclusion, and (4) statistical control, and (5) randomization.
What are the 12 threats to internal validity?
These threats to internal validity include:
ambiguous temporal precedence, selection, history, maturation, regression, attrition, testing, instrumentation, and additive and interactive threats
to internal validity.
What is an example of external validity?
External validity is another name for the generalizability of results, asking “whether a causal relationship holds over variation in persons, settings, treatments and outcomes.”
1
A classic example of an external validity concern is
whether traditional economics or psychology lab experiments carried out on college
…
