The "ISO 16269-4:2010 Statistical interpretation of data Part 4: Detection and treatment of outliers, Generalised Extreme Studentized Deviate" should be quoted as a Rreference. This does not contain the limitations of the Grubb's test.
Possessives with names ending in s[edit]
Many people do not understand how to use apostrophes and think that any word ending in an "s" is appended with only an apostrophe. That's not the rule, and it never was.
This is Grubbs's test. If you need confirmation, see scholarly articles describing it: https://doi.org/10.2307/3315459 and https://doi.org/10.2307/2528714 for example.
If you need to review style rules, see one of many style guides. Here's a quote from MW: "For names that end in an s or z sound, though, you can either add -'s or just an apostrophe. Going with -'s is the more common choice: the car that belongs to Jones → Jones's car or Jones' car" (https://www.merriam-webster.com/grammar/what-happens-to-names-when-we-make-them-plural-or-possessive). 140.141.192.46 (talk) 15:38, 18 January 2024 (UTC)
