statcheck: Extract Statistics from Articles and Recompute P-Values

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. If the reported p-value is statistically significant and the recomputed one is not, or vice versa, the result will be flagged as a decision error. You can use statcheck directly on a string of text, but you can also scan a PDF or HTML file, or even a folder of PDF and/or HTML files. Statcheck needs an external program to convert PDF to text: Xpdf. Instructions on where and how to download this program, how to install statcheck, and more details on what statcheck can and cannot do can be found in the online manual: <https://rpubs.com/michelenuijten/statcheckmanual>. You can find a point-and-click web interface to scan PDF or HTML or DOCX articles on <http://statcheck.io>.
