Ok, neat, but I wonder what's the conclusion. Should I understand more more money equals better education or that more math education equals more money?
I'd wager it's the first one, since inequality sucks. Also, that oil beats schooling, looking at the bottom right corner.
The best we can say for that chart is that there is some relation (not necessarily casual) between GDP and mathematical education levels.
The causal factor could be anything - but it's a damn pretty curve. It at least suggests that measuring a country's gdp can give you a ballpark figure for it's mathematical education levels.
Might be a novel premise for funding to explore if math is a causal factor.
There's probably a better number than GPD/pop, considering the big outliers have exceptional inequality or equality in vietnam's case.
There's probably a much better line between median (or even better yet, first quartile) education funding and math scores, and a similar correlation to OP between GDP and education funding.
Feel free to create a post with the better numbers if you have them!
Could also be education - rising tide lifts all boats thing - rather than mathematics specifically.
Why is China listed multiple times as individual cities/regions?
What is the missing footnote for all those asterisks?
Hong Kong and Macau are weird in that they're part of China but have a different government and separate economic system. They're both former European colonies that were "given" back relatively recently. I don't see the main part of China on the graph, but maybe I just missed it.
Here is the source: https://www.oecd-ilibrary.org/education/pisa-2022-results-volume-i_53f23881-en
For the asterisk:
- Caution is required when interpreting estimates because one or more PISA sampling standards were not met (see Reader’s Guide, Annexes A2 and A4). Long-term trends are reported for the longest available period since PISA 2003 for mathematics, PISA 2000 for reading and PISA 2006 for science. The OECD average does not include Costa Rica and Spain for short-term change in performance.
I'm looking for China, IIRC they only allowed Hong Kong and Macao to participate, the rest of China did not
"Chinese Taipei"
You (the author, not OP) mean Taiwan?
What's up with Ireland ?
Very high GDP per capita due to large tech companies having their European HQ there to avoid taxes
