Eighty percent of those polled in many surveys make this mistake. The p-value of a test is the probability of obtaining a result like the one obtained in the investigation if the null hypothesis is true. The probability of a pregnancy involving three embryos is very small, at 0.00008 (8 in 100,000). In pregnancies with triplets, the probability of a caesarean section being performed is very high, at 0.98 (98%). These are two very different values, and two very different concepts. Saying that 0.98 is the probability of a pregnancy involving triplets would be a serious mistake. We make the same mistake when we say that the p-value of the test is the probability that the null hypothesis is true, or the probability that it is false.<\/jats:p>","DOI":"10.33588\/rn.7910.2024318","type":"journal-article","created":{"date-parts":[[2024,11,29]],"date-time":"2024-11-29T08:10:46Z","timestamp":1732867846000},"source":"Crossref","is-referenced-by-count":1,"title":["The p-value of a test is not the probability that the null hypothesis is true or false"],"prefix":"10.31083","volume":"79","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3782-2772","authenticated-orcid":true,"given":"C","family":"Carazo-D\u00edaz","sequence":"first","affiliation":[{"name":"Universidad Cat\u00f3lica de Murcia, Murcia, Espa\u00f1a"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L","family":"Prieto-Valiente","sequence":"first","affiliation":[{"name":"Universidad Cat\u00f3lica de Murcia, Murcia, Espa\u00f1a"},{"name":"Sociedad Cient\u00edfica de Investigaci\u00f3n Biom\u00e9dica, Palma de Mallorca, Espa\u00f1a"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"16242","published-online":{"date-parts":[[2024,11,16]]},"container-title":["Revista de Neurolog\u00eda"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.imrpress.com\/journal\/RN\/79\/10\/10.33588\/rn.7910.2024318","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,12,2]],"date-time":"2024-12-02T11:31:40Z","timestamp":1733139100000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.imrpress.com\/journal\/RN\/79\/10\/10.33588\/rn.7910.2024318"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,11,16]]},"references-count":0,"journal-issue":{"issue":"10","published-print":{"date-parts":[[2024]]}},"alternative-id":["S0210-0010(24)00020-3"],"URL":"https:\/\/doi.org\/10.33588\/rn.7910.2024318","relation":{},"ISSN":["0210-0010","1576-6578"],"issn-type":[{"type":"print","value":"0210-0010"},{"type":"electronic","value":"1576-6578"}],"subject":[],"published":{"date-parts":[[2024,11,16]]},"article-number":"289"}}
