Description: 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>.
