Reproducibility
open-in-new
<p>Reproducibility, closely related to replicability and repeatability, is a major principle underpinning the <a href="/facts/Scientific_method/182j8RWE">scientific method</a>. For the findings of a study to be reproducible means that results obtained by an <a href="/facts/Experiment/esltM54f">experiment</a> or an <a href="/facts/Observational_study/zEhxI4eh">observational study</a> or in a <a href="/facts/Statistical_analysis/sJLjubxm">statistical analysis</a> of a <a href="/facts/Data_set/eDvegUTK">data set</a> should be achieved again with a high degree of reliability when the study is replicated. There are different kinds of replication but typically replication studies involve different researchers using the same methodology. Only after one or several such successful replications should a result be recognized as scientific knowledge. </p>
