What might link these
The relationship between the age 14 female population and the number of female repeaters in primary education might be influenced by factors such as education quality or socio-economic status. A careful reader should consider that cultural attitudes towards female education could be a likely confounder. The correlation suggests a potential area for further investigation.
Why this is not proof of anything
This is a correlation across countries, not an experiment. It cannot show that either indicator causes the other, and both may simply follow a third thing. This correlation could mislead by implying a direct relationship between the two indicators without accounting for other influential factors.
The second figure above repeats the measurement with national population and income held constant. It is the more conservative number: a relationship that largely disappears there was mostly telling you that larger, richer countries have more of most things.
How this was measured
Both indicators were ranked across every country reporting each, and the two rankings compared — ranks rather than raw values, because a handful of very large countries can otherwise manufacture a relationship on their own. The calculation is arithmetic over figures already published on this site; the commentary above is drafted from the two indicator names and the resulting coefficients.
