Quotes are copied from the page, 25 words or fewer; an em dash inside a quote is shown as a hyphen. The page text itself is not kept. A hop page's text was searched up to the grader's text limit, so "not found" means not found in the text read.
What every kind and letter means
Kinds
- primary
- the page is the origin of its own numbers (a statistical agency, a journal, a filing, or a page that states its own study and sample).
- secondary
- at least half of the page's statistic and number claims are cited: by a link, a footnote, a source named from the grader's primary source list, or one of two page-level rules noted on the grade page.
- repackaging
- fewer than half of the page's statistic and number claims are cited.
- content farm
- the page carries three or more content-farm marks (such as no author, no date, unrelated topics, heavy ads) and under a quarter of its numbers have a link or a footnote.
- unknown
- the page could not be graded (robots.txt says no, the page could not be fetched, or it had too few claims).
Letters
- A
- the page is primary, or at least 90% of its checked claims were found on a primary page.
- B
- at least 70% of checked claims were found on a primary page, or at least 90% trace.
- C
- at least 40% of checked claims trace.
- D
- at least 10% of checked claims trace, or most checked claims cite a source that could not be fetched or that the site's robots.txt rules out.
- F
- under 10% of checked claims trace, with 3 or more claims checked.
- no letter
- a page that is not primary needs at least one checked claim for a letter, and a page of kind unknown gets none. An F needs 3 checked claims.
A claim is checked when the grader tried its first link: it read the page, could not fetch it, or found that the site's robots.txt rules it out. It traces when that link led to a primary page with the number, to a page on a primary-source site where the number was not found, or to another page that has the number.
The primary source list is a fixed list in the grader: 56 sites (statistical agencies, central banks, international bodies, survey houses, journals and preprint servers), the organizations behind them, and ADP's employment report.
