What is direct replication of a study?
Direct replication is defined as attempting to reproduce a previously observed result with a procedure that provides no a priori reason to expect a different outcome (Open Science Collaboration, 2015; Schmidt, 2009).
What are the three types of replication studies?
Virtual, operational, direct, and retest are terms used to indicate that a study is closely replicated. This strategies aproximate the original research design. Type 3. Systematic extension, constructive, systematic, and independent replications include the extension of an earlier study.
What is the difference between direct and systematic replication?
DIRECT REPLICATION: means to do the study exactly the same way as before. SYSTEMATIC REPLICATION: means to do the study with some variation as compared to before (change population, setting, stimuli, behavior studied, etc.).
Can you replicate a research 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.
How do you know if a study has been replicated?
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 is the purpose of replication in an experiment?
In statistics, replication is repetition of an experiment or observation in the same or similar conditions. Replication is important because it adds information about the reliability of the conclusions or estimates to be drawn from the data.
What is exact replication?
Exact Replication (also called Direct Replication) A scientific attempt to exactly copy the scientific methods used in an earlier study in an effort to determine whether the results are consistent. The same—or similar—results are an indication that the findings are accurate.
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.
How can a study be replicated?
A replication study involves repeating a study using the same methods but with different subjects and experimenters.
Why is it important for research to be replicated?
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.
