::::It says "most cats", indeed, but the above was about Obama, singular. Though I think it's covered anyway...

:::::All the statements about 'Barack Obama' ought to be medium precision at best, because there could be more than one Barack Obama, and it doesn't give any further contextualisation to identify, for example 'the Barack Obama who was president of the United States of America'.

Someone should add an explanation of the difference between precision and accuracy.

:I don't get your point?

::The only thing I can imagine is, that these kinds of numbers happen due to conversions. E.g. 6ft1in would be 185.42cm (according to the first calculator I found), but it is unlikely that 6ft1in was as precise as a cm-value with 2 digits after the decimal point would be. And in the other direction 185cm (which would be the usual precision of a height in m or cm - while 186cm could still be correct as it would be 6ft1in in the "usual precision") would calculate as 6ft and 0.83in --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 10:18, 11 November 2022 (UTC) | ::The only thing I can imagine is, that these kinds of numbers happen due to conversions.

I'm not sure the current explanation's claim that 'being too precise usually decreases accuracy' is, er, accurate (or perhaps it's just imprecise). It might be reasonable to claim that increasing precision tends to decrease accuracy relative to the level of precision, but not so much in absolute terms, or even necessarily relative to the size of the thing being measured.[[Special:Contributions/141.101.107.156|141.101.107.156]] 09:38, 11 November 2022 (UTC) | I'm not sure the current explanation's claim that 'being too precise usually decreases accuracy' is, er, accurate (or perhaps it's just imprecise).

::It gets even better when different units also use different 0s. So for a persons height we can assume that as 0ft0in and 0cm is the same, 185cm is one order of magnitude more precise than 6ft1in, as it is 3 significant digits vs 2 at the same height. However a persons body temperature in 38°C with 2 significant digits and 311K with 3 is the same level of precision and only .15°C (Or .15K) apart, while 100°F (37.77...°C) is also very close but a bit more precise. --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 14:10, 11 November 2022 (UTC) | ::It gets even better when different units also use different 0s.

I was expecting maybe a reference to Schrödinger's President when I first read the comic - but later realized that this could have been misconstrued as a threat.

As far as I recall, isn't the transcript supposed to avoid tables? I understand blind people with text reading programs use the transcripts to follow this comic, and thus it should avoid visual elements wherever possible?
