This seems to be a very controversial topic. Although Wikipedia uses t-test and p-value, there are those who argue that the correct is "t test" and "p value". See for instance the recommendations from APA: https://blog.apastyle.org/apastyle/2011/08/the-grammar-of-mathematics-writing-about-variables.html I myself have seen this written both with and without hyphens and I really don't know which is the correct one. If anyone can give a definitive answer about this issue, please step forward. It should be noted that in the help we have "t-test" written with a hyphen 16 times. https://opengrok.libreoffice.org/xref/help/source/text/scalc/01/statistics_test_t.xhp Whereas in the UI there are 4 strings that do not use hyphen. https://opengrok.libreoffice.org/xref/core/sc/inc/scfuncs.hrc So we need to decide which one is correct and maintain consistency.
I didn't know about the controversy. I wonder if this is related to unhyphenated spellings of compound words often being preferred in American English? Using a lowercase t consistently would be an improvement in any case.
APA seems to prefer "t test" when on its own, but "t-test" when used as a compound adjective preceding the term it qualifies: https://apastyle.apa.org/learn/faqs/when-use-hyphen On the other hand, Wikipedia seems to consistently use "t-test", "t-distribution" and "t-value" with few exceptions. If we go by popularity, the hyphenated version is a clear winner in the English-speaking world: https://books.google.com/ngrams/graph?content=t+test%2Ct-test%2CT+test%2C+T-test&year_start=1900&year_end=2019&corpus=en-2019&smoothing=3 (same goes on NGrams for Spanish, French, German) In any case, I think it should _not_ be capitalised like it currently is in the UI. I would suggest using "t-test" in the UI to match the documentation and what's currently more popular.
Proposed fix here: https://gerrit.libreoffice.org/c/core/+/149598 I guess these are all the occurrences of "T test" in the UI.
The hyphen is not only useful in compound adjectives, but also in compound nouns when one of the components is a single letter.
