Prior to analyzing the complete data set, a time-stamped preregistration was posted in an independent, third-party registry for the data analysis plan.
The study was preregistered...
Explain
The preregistration fully describes...
the intended statistical analysis for each research question (this may require, for example, information about the sidedness of the tests, inference criteria, corrections for multiple testing, model selection criteria, prior distributions etc.).
Comments about your Preregistration
The manuscript fully describes...
the rationale for the sample size used (e.g., an a priori power analysis).
the study design, procedures, and materials to allow independent replication.
the measures of interest (e.g., friendliness) and their operationalizations (e.g., a questionnaire measuring friendliness).
any changes to the preregistration (such as changes in eligibility criteria, group membership cutoffs, or experimental procedures).
Comments about your Methods section
The manuscript...
distinguishes explicitly between "confirmatory" (i.e., prespecified) and "exploratory" (i.e., not prespecified) analyses.
