The explanation builds on definitions of terms in statistics.  That's fine, but there are also non-statistical usages, just for example whether someone has now (or had before) the COVID-19 virus.  A false positive is a test result which incorrectly indicates that a particular condition or attribute is present, and a false negative is a test result which incorrectly indicates that a particular condition or attribute is absent.  A particular test is useful when its incidence of Type I and II errors is low.  Types III and IV in that context would be given by poorly designed tests which, even if they give correct results, do it for unsupportable reasons and are therefore unreliable for future results.  Types V, VI, VII, and VIII are necessary fillers in the sequence, once you decide that calling The Rise of Skywalker a mistake has to be error type IX simply because it's the ninth film in the series.

As of the time of this post, the title text is "Type IIII error: Mistaking tally marks for Roman neumerals". Is "neumerals" a typo, or is there a joke in there that I'm missing? Cosmogoblin (talk) 22:52, 6 May 2020 (UTC)

Looks like a typo to me. Randall's patrons should have caught this for him!

That particular mistake is actually just called a type error.

The explanation builds on definitions of terms in statistics. That's fine, but there are also non-statistical usages, just for example whether someone has now (or had before) the COVID-19 virus. A false positive is a test result which incorrectly indicates that a particular condition or attribute is present, and a false negative is a test result which incorrectly indicates that a particular condition or attribute is absent. A particular test is useful when its incidence of Type I and II errors is low. Types III and IV in that context would be given by poorly designed tests which, even if they give correct results, do it for unsupportable reasons and are therefore unreliable for future results. Types V, VI, VII, and VIII are necessary fillers in the sequence, once you decide that calling The Rise of Skywalker a mistake has to be error type IX simply because it's the ninth film in the series.
