Editing Talk:701: Science Valentine

If he really did figure out, by sitting down and thinking his life and their relation through, that he doesn't really love her, then he did the right thing. Of course he may not have been scientific enough, if the reasons his feelings and happiness decreases is caused by some outside agency... --[[User:Kynde|Kynde]] ([[User talk:Kynde|talk]]) 11:56, 29 April 2015 (UTC)


I think the r0, r1, r2 are correlation coefficients.  They are all between -1 and 1, and all called r, which is a common name for a correlation coefficient.  Also, this would mean r2 shows a strong negative correlation between two things. --[[Special:Contributions/108.162.215.39|108.162.215.39]] 06:57, 11 May 2015 (UTC)

I agree with the above comment, great explanation for this statistical variable which shows that his love becomes negatively correlated with time, complementing the first panel's graph. [[User:Barrtender|Barrtender]] ([[User talk:Barrtender|talk]]) 14:26, 16 September 2015 (UTC)

:I also think that the correlation coefficient interpretation is right. Moreover, it looks like r0 refers to the time just after the first meeting (slightly positive trend), r1 to the time when they were dating (negative trend) and r2 to the time after engagement (with even stronger negative trend). --[[Special:Contributions/198.41.242.245|198.41.242.245]] 18:26, 3 December 2015 (UTC)


Maybe [[833: Convincing]] would be worth mentioning in the explanation, where Megan draws a relationship themed graph (and Cueball complains about missing axis lables) -- [[User:Ruffy314|Ruffy314]] ([[User talk:Ruffy314|talk]]) 02:35, 3 November 2015 (UTC)

This reminds me of Ted Chiang's short story, ''Division By Zero,'' where a character looks for proof of love and finds none, deciding he doesn't love them... Though I interpreted the end as positive, if a little ambiguous. Ted Chiang is a great author for XKCD fans, I think.

I am pretty damn sure (and am surprised it was not corrected before) that correlation is not of v1 or v2 to t, but v1 to v2 (over t). [[Special:Contributions/162.158.238.9|162.158.238.9]]M-ree

The phrase "Charts and Graphs" could be a reference to the song Nothing Better by The Postal Service, which would be fitting as it's a song about a similar scenario. "I've made charts and graphs that should finally make it clear / I've prepared a lecture on why I have to leave" The album was released in 2003 so the timing works.[[Special:Contributions/172.70.114.159|172.70.114.159]] 19:02, 30 November 2021 (UTC)
