Replication is a term referring to the repetition of a research study , generally with different situations and different subjects, to determine if the basic findings of the original study can be applied to other participants and circumstances.
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 are the different types of replication studies?
There are two types of replication Blomquist1986: literal and construct . In a literal replication, the researcher uses the same measures with the same type of subjects, and controls the same conditions. The original study is replicated as exactly as possible.
Are replication studies rare?
Hence, replication studies are carried out and published very rarely as compared to original studies . Can I redo research done earlier by somebody else and... Since replication studies are considered an important aspect of scientific progress, some researchers think that the general outlook toward them should change.
What is the main purpose of a replication study?
This definition reduces emphasis on operational characteristics of the study and increases emphasis on the interpretation of possible outcomes. The purpose of replication is to advance theory by confronting existing understanding with new evidence .
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.
Why is replication so important?
If research results can be replicated, it means they are more likely to be correct. Replication is important in science so scientists can “check their work .” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.
What is a successful replication?
A successful replication study is a study that also produces a significant result . Obtaining two significant results is akin to making two free throws. ... That is, the original study produced a significant result (success) and the replication study produced a non-significant result (failure).
What are the steps of replication?
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment . During separation, the two strands of the DNA double helix uncoil at a specific location called the origin.
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 are the two types of replication stats?
The two types of replications are exact replications and conceptual replications . An attempt to replicate precisely the procedures of a study to see whether the same results are obtained. A conceptual replication is the use of different procedures to replicate a research finding.
What is the difference between repetition and replication?
Repetition occurs when multiple sets of measurements are made during one scientific investigation. ... Replication occurs when a scientific investigation is reproduced by another person. Repetition is multiple trails, when replication is when you redo the entire experiment.
What is replication mean in English?
1 : the action or process of reproducing or duplicating replication of DNA . 2 : performance of an experiment or procedure more than once. replication. noun.
What makes a good replication 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.
Can a study be replicated?
A replication study involves repeating a study using the same methods but with different subjects and experimenters.
Where does DNA replication occur?
DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes . Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions.
