Multiverse analysis is a scientific method that specifies and then runs a set of data-analytical choices, plausible alternative models or statistical tests for a single hypothesis. It is a method to address the issue that the "scientific process confronts researchers with a multiplicity of seemingly minor, yet nontrivial, decision points, each of which may introduce variability in research outcomes".
