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.
How are studies replicated?
When research papers are published, they describe their methodology, so other researchers can copy it (or vary it) and build on the original research. When another research team tries to conduct a study based on the original to see if they find the same result, that’s an attempted replication.
What makes a study replicable?
Research is replicable when an independent group of researchers can copy the same process and arrive at the same results as the original study . ... Empirical generalizations are results that cannot be replicated by independent researchers using valid, but different, methods.
Do you need permission to replicate a study?
It is a violation of copyright law to use an instrument without permission. Additionally, you must give due credit in the dissertation to the study you are replicating .
What makes a good replication study?
Evaluating the replication should involve reporting two tests: 1) the size, direction and confidence interval of the effect , which tell us whether the replication effect is significantly different from the null; 2) an additional test of whether it is significantly different from the original effect.
How do you ensure a study is replicable?
- Drilling down to a specific question of interest with a corresponding, measurable quantity.
- Collecting a representative sample of the population of interest by randomizing appropriately.
- Identification of the appropriate statistical model for your data and experimental design.
How do you know if you can replicate a study?
The most direct method to assess replicability is to perform a study following the original methods of a previous study and to compare the new results to the original ones .
What happens if a study Cannot be replicated?
If a finding can’t be replicated, it suggests that our current understanding of the study system or our methods of testing are insufficient . ... When a study cannot be replicated, it suggests that our current understanding of the study system or our methods of testing are insufficient.
Can a study be replicated?
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 percent of studies can be replicated?
The study estimated with 95% confidence that “results might be reproduced for only 0.6% to 6.8% of all 1,989 articles”.
What are the two types of replications?
There are two types of replication Blomquist1986: literal and construct .
What type of study is a descriptive study?
What is Research? A descriptive study is one in which information is collected without changing the environment (i.e., nothing is manipulated). Sometimes these are referred to as “ correlational ” or “ observational ” studies.
What is a replication 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 . 14 . Clearly, this definition requires some explanation.
What is the main purpose of a replication study?
Replication is a study for which any outcome would be considered diagnostic evidence about a claim from prior research . This definition reduces emphasis on operational characteristics of the study and increases emphasis on the interpretation of possible outcomes.
What is an example of replication?
Replication is the act of reproducing or copying something, or is a copy of something. When an experiment is repeated and the results from the original are reproduced , this is an example of a replication of the original study. A copy of a Monet painting is an example of a replication.
How do you write replication?
Write for a broad audience and general interest. Limit jargon and write clearly and concisely . Your readers may not be familiar with the original replication paper or the literature in general. Give your reader enough back- ground to understand how your analysis fits in.
