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 tests (NHST) in APA style (e.g., t(28)
= 2.2, p < .05), using pattern-matching ("regular expressions"). 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 computed
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. PDF files are converted to
text using the R package 'pdftools', so no additional software installation is
necessary. You can find more information on what 'statcheck' can and cannot do
and a point-and-click web interface to scan PDF or HTML or DOCX articles on
<https://statcheck.io>.
