“Replication is a central tenet of science; its purpose is to confirm the accuracy of empirical findings, clarify the conditions under which an effect can be observed, and estimate the true effect size,” begin the authors of “Investigating Variation in Replicability.”

2023年9月26日 · Replication refers to the repetition of a research study, generally with different situations and subjects, to determine if the basic findings of the original study can be applied to other participants and circumstances.

The replication study if carried out carries the potential to empirically support the results of the original study, either by clarifying issues raised by the original study or extending its generalizability.

2015年7月27日 · We discuss each goal conceptually, explain appropriate analysis procedures, and provide 1 or more examples to illustrate these analyses in practice.

Using a validated machine learning model that estimates a paper’s likelihood of replication, we found evidence that both supports and refutes speculations drawn from a relatively small sample of manual replications.

2024年9月11日 · In psychological science, replicability—repeating a study with a new sample achieving consistent results (Parsons et al., 2022)—is critical for affirming the validity of scientific findings.

2022年1月31日 · We provide an overview of the number of replication studies by replication type, year, outcome, authorship, and journal. Our results are consistent with those of Makel and Plucker, revealing very low but gradually increasing rates of replication study in education.

2023年6月6日 · When conducting a replication study, the aim is to design, report, and compare a piece of research that repeats a previous study in some way. The most critical step in the planning and conduct of a replication project is how to identify a study to replicate.

2020年3月17日 · Two types of statistical replication evidence and four types of statistical nonreplication evidence are described. In addition, three types of inconclusive statistical replication evidence...

2024年9月15日 · Simply put, it’s the process of repeating a study using the same methods as the original research. The goal is to see if the same results can be obtained, thus confirming the validity of the original findings.
