statcheck on the web
statcheck is a "spellchecker" for statistics. It checks whether your p-values match their accompanying test statistic and degrees of freedom. statcheck searches for null-hypothesis significance test (NHST) in APA style (e.g., t(28) = 2.2, p < .05). It recalculates the p-value using the reported test statistic and degrees of freedom. If the reported and computed p-values don't match, statcheck will flag the result as an error.
How can I use the statcheck web app?
The statcheck web app is a simple interface that calls on the statcheck R package in the background. To use the web app, all you need is a working internet connection. You don't need R, or even know how to work with R.
Simply go to the website at https://statcheck.io and upload a paper in .pdf, .html, or .docx format. Statcheck will search your document for statistics and returns a table with all detected statistics and whether they are internally consistent or not.
Where can I find more information?
- The manual: A detailed instruction manual with information on what statcheck can and cannot do, information on how to install and use the statcheck R package, and more.
- The GitHub page: Here you can find statcheck's latest developments.
- The R package: The R package has additional functionality which allows you to change more settings and to scan entire folders of papers.
- The paper: The seminal paper in which statcheck was introduced. We ran statcheck on over 30,000 psychology papers and report general inconsistency-prevalences over time and per journal.
- The validity study: We compared statcheck's performance with manual checks and assessed its accuracy in classifying results as consistent/inconsistent
