What is the difference between replication and repetition? A progressive research program (the left path) succeeds in replicating findings across conditions presumed to be irrelevant and also matures the theoretical account to more clearly distinguish conditions for which the phenomenon is expected to be observed or not observed. In engineering, science, and statistics, replication is the repetition of an experimental condition so that the variability associated with the phenomenon can be estimated. Using the same procedures is an interim solution for not having clear theoretical specification of what is needed to produce evidence about a claim. The study was conducted in a particular climate, at particular times of day, at a particular point in history, with a particular measurement method, using particular assessments, with a particular sample. ASTM, in standard E1847, defines replication as ". It is always possible that it was real, and we cannot identify or recreate the conditions necessary to replicate successfully. In each experiment, five measurements are taken at each combination of factor settings. On the other hand, replication occurs when an experiment is reproduced by different experimental runs. Replication Repetition Teaching Resources | TPT - TeachersPayTeachers How do we decide whether something is a replication? Having confronted the complex transmission histories of the poems of Byron, Keats and Shelley, and the 'multiple authorities' implicit in the production of many Romantic texts, editors such as Jerome McGann, Jack Stillinger and Donald Reiman started reconsidering the idea of 'final authorial .

The ambiguity between disconfirming an original claim or identifying a boundary condition also means that understanding whether or not a study is a replication can change due to accumulation of knowledge. I found that students have difficulty writing inside the circles, so I made a Docs Venn Diagram using rectangles instead of circles. Replication Steve was given a set of 5 metal cubes. white glue students will make slime. When theories are too immature to make clear predictions, repetition of original procedures becomes very useful. Repetition happens when measurements are taken during the same experimental run, which means that the same person runs the experiment in multiple trials. Replication is the process of creating an identical copy of something, while repetition is the act of doing something multiple times. 2 Repetition (noun) : The act of performing a single, controlled exercise motion. These recommendations have been motivated by several high profiles examples of studies being either retracted or not repeatable. A complete theoretical account eliminates generalizability space because the theoretical expectations are so clear and precise that all tests are replication tests. For use as part of an interactive notebook. These are generalizability tests. https://doi.org/10.1371/journal.pbio.3000691.g002. 4 0 obj The measurement of an angle by successive observations with a repeating instrument. When we talk about replication in research, we are usually referring to the replication of an entire study. Once we have repeated our testing over and over, and think we understand the results, then it is time for replication.

Page 1 has the Reading Paragraphs. In the context of data, repetition can refer to storing the same data in multiple places, or repeating a process (such as running a query) multiple times. Required fields are marked *. Replication, on the other hand, is the act of repeating the entire experiment, from start to finish, in order to verify the validity of the results. Necessary cookies are absolutely essential for the website to function properly. Comes complete with 5 ELA-style question. Fig 1s left panel illustrates a discovery and conditions around it to which it is potentially generalizable. Because replication is defined based on theoretical expectations, not everyone will agree that one study is a replication of another. According to common understanding, replication is repeating a studys procedure and observing whether the prior finding recurs [7]. It is very important that research can be replicated, because it means that other researchers can test the findings of the research.

Designing a replication with a different methodology requires understanding of the theory and methods so that any outcome is considered diagnostic evidence about the prior claim. Why is replication important in science? Vegas [7], replication is ''the repetition of an experiment to double-check its results". In scientific research, replication is essential in order to confirm that results are accurate and not just a fluke. Perspectives Video: Experts, 2 Repetition requires the experiment to be repeated at least three times and replication requires the experiment to be conducted by another researcher. This definition of replication is intuitive, easy to apply, and incorrect. Credibility of scientific claims is established with evidence for their replicability using new data [1].
