What does it mean when a study cannot be replicated by an independent researcher?
The replication was done incorrectly
.
Why is it bad if a study is not replicable?
“A
lack of
reproducibility may also indicate that we don’t understand parts of the experiment well enough yet and so it’s difficult to reproduce all of the relevant parts, because we don’t know what they are, and then we change a couple of parameters that we thought didn’t matter.”
Why is it important for scientists to be able to replicate the results of a study?
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 to replicate a research study?
A replication study is a study that is
an independent repetition of an earlier, published study, using sufficiently similar methods (along the appropriate dimensions) and conducted under sufficiently similar circumstances
.
What is replication in research and why is it important?
Replication is one of
the most important tools for the verification of facts within the empirical sciences
. Any piece of research must be repeated by other investigators before its findings can be considered as reasonably well established. [Replicability] gives credibility to the conclusions of scientific research.
What does it mean if a study Cannot be replicated?
Scientists aim for their studies to be replicable — meaning that another researcher could perform a similar investigation and obtain the same basic results. When a study cannot be replicated, it suggests
that our current understanding of the study system or our methods of testing are insufficient.
Why research can be replicated but its finding Cannot be duplicated?
It is very important that research can be replicated, because it means
that other researchers can test the findings of the research
. Replicability keeps researchers honest and can give readers confidence in research. … If the research is replicable, then any false conclusions can eventually be shown to be wrong.
Why is it important for scientists to be able to replicate the results of a study quizlet?
Which one of the following methods do scientists use to analyze the data they gather from their studies? … Why is it important for scientists to be able to replicate the results of a study?
they need to confirm the findings of the original study
. Which of the following is a problem associated with volunteer bias?
Is the research study Cannot be replicated or repeated because it is unique in every case?
Quantitative data are more credible, reliable, and useful than qualitative data. The research study cannot be replicated or repeated because it is unique in every case. Data are in the form of numbers and analyzed statistically. … The behavior of the participants is observed and is critical to the analysis of results.
How do you know if a study can be replicated?
Research is
replicable when an independent group of researchers can copy the same process and arrive at the same results as the original study
. Hence, establishing its validity.

Does exploratory research always lead to conclusive research?
Exploratory type of research is usually conducted to have a better understanding of the existing problem, but
usually doesn’t lead to a conclusive result
. … Also referred to as interpretative research or grounded theory approach, the outcomes of this research provide answers to questions like what, how and why.
When can you replicate a study?
A research can
be replicated because it is made by different researchers and explorers
. It is possible that a researcher shared his/her idea with another person. It can also be broadcasted and written for everyones added information. A finding, however, is completely original and cannot be replicated or duplicated.
What are limitations in replicating quantitative research?
One of the limitations of quantitative research is that
it’s narrow focus means relationships and larger contexts can be missed
, but the scientific method provides an escape hatch for quantitative research, the ability to replicate the study in another setting. …
What caused the replication crisis?
There is a broad agreement that psychology is facing a replication crisis. Even some seemingly well-established findings have failed to replicate. Numerous causes of the crisis have been identified, such as
underpowered studies, publication bias, imprecise theories, and inadequate statistical procedures
.
Why is replication important when designing an experiment?
replication means that each treatment is used more than once in an experiment. Important because
it allows us to estimate the inherent variability in the data
. This allows us to judge whether an observed difference could be due to chance variation.
What is a problem associated with volunteer bias?
The term volunteer bias refers to a specific bias that can occur when the subjects who volunteer to participate in a research project are different in some ways from the general population. … An underlying problem in volunteer bias is that
volunteers and nonvolunteers
are different in important ways.
In which study the conditions of a system or process are replicated?
A replication study involves repeating a study using
the
same methods but with different subjects and experimenters.
Which can be replicated but not the findings Why?
A research can be replicated because it is made by different researchers and explorers. It is possible that a researcher shared his/her idea with another person. It can also be broadcasted and written for everyones added information.
A finding
, however, is completely original and cannot be replicated or duplicated.
What is the difference between replication and duplication?
The main difference between replication and duplication of DNA is that
replication is the synthesis of an exact replica of DNA
while duplication is the doubling of the amount of DNA as a result of replication.
What is the purpose of replication studies quizlet?
A replication study
in which researchers repeat the original study as closely as possible to see whether the original effect shows up in the newly collected data
. Also called exact replication. See also conceptual replication, replication-plus-extension.
What is one benefit of conducting a replication with extension instead of a replication?
What is one benefit of conducting a replication with extension instead of a replication? A replication with extension
is more likely to be published than a replication
.
Why is quantitative research not flexible?
Generally,
quantitative methods are fairly inflexible
. With quantitative methods such as surveys and questionnaires, for example, researchers ask all participants identical questions in the same order. The response categories from which participants may choose are “closed- ended” or fixed.
Can quantitative research be replicated?
Replication is a cornerstone of quantitative research because
it detects fraud or findings that lack internal validity
. … When such replication occurs, it strengthens the external validity of the original study’s findings.
Does analysis of data is less time consuming?
Also, data analysis is
relatively less time consuming
(using statistical software). Useful for decision making: Data from quantitative research—such as market size, demographics, and user preferences—provides important information for business decisions.
Do you need permission to replicate a study?
If you are able to replicate a study for your dissertation, remember that
you are required to get permission to use the instrument from the original creator of the dissertation
. … Additionally, you must give due credit in the dissertation to the study you are replicating.

, or to the defendant’s answer in a suit in Equity. When the defendant raised a new point in his or her response, the plaintiff was required to introduce an additional fact that defeated this new point. …
What are replicates in an experiment?
Replicates are
multiple experimental runs with the same factor settings (levels)
. Replicates are subject to the same sources of variability, independently of each other. … The design of an experiment includes a step to determine the number of replicates that you should run.
What does a researcher do when he replicates a study in writing a topic for research?
Replicate:
Conduct the study again with different samples or in different settings to see if you get the same results
.
Can qualitative research be replicated?
We define what a replication of a qualitative study can potentially entail and espouse that such replications should, by all means, be attempted. … Hence findings of
quantitative studies can be replicated
and generalized to larger populations whereas qualitative findings only hold for and describe the individual cases.
What are the two types of conclusive research?
-
Descriptive or statistical research, and.
-
Causal research.
How exploratory research is different from conclusive research?
The key difference between the two research methods is that exploratory research is used to gain a better understanding of a research problem while
conclusive research is used to arrive at results or decisions
. … Exploratory research, on the other hand, relies more so on qualitative data.
When should conclusive research be used?
As the term suggests, conclusive research is meant to
provide information that is useful in reaching conclusions or decision-making
. It tends to be quantitative in nature, that is to say in the form of numbers that can be quantified and summarized.
What does lack of generalizability mean?
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.
