Pronunciation

The article presently says that the pronunciation of "Pearson" is /ˈpɪərsən/. This is surely incorrect. In my dialect, the natural way to say it would be more like /ˈp[invalid input: 'iəɹ']sən/, where the first schwa is debatable; notice the change to the first vowel and the rhotic. Indeed, this is how I have heard it pronounced throughout my personal experience.

Can we get a citation on the proper pronunciation or something? IbexNu (talk) 23:45, 28 August 2021 (UTC)[reply]

Concur. I would just "edit aggressively", in good WP fashion, if I were you, IbexNu. Jmacwiki (talk) 20:18, 29 January 2023 (UTC)[reply]

Wrong standard error formula

The formula given is wrong. There should be no square root over 1-r^2. This can be seen from the sources given Bowley, A. L. (1928). "The Standard Deviation of the Correlation Coefficient". Journal of the American Statistical Association. 23 (161): 31–34. doi:10.2307/2277400. ISSN 0162-1459. JSTOR 2277400. "Derivation of the standard error for Pearson's correlation coefficient".

Meaning of the term "product moment"

The text seems to indicate that the expression"product moment" doesn't mean a "multiplication of moments". However it is a weird sentence and is hard to understand what it means. Can an editor, who has the required knowledge on the subject, edit that sentence and change it with a more clear and meaningful one? What does product mean there? What does "moment" mean there? And what does "product moment" eventually mean? 78.162.44.128 (talk) 17:50, 9 June 2025 (UTC)[reply]
