I think the author of the parent post to yours meant that if an average or aggregate grade of some kind is calculated for the whole of the USA, then the resulting figure may not reflect the performance of much of the country because of a large variation between the states.
Of course, many of the countries in the study have populations smaller than some states within the USA. Perhaps the comparisons should be conducted at state level?
- Gormo 14y agoWhich makes one wonder as to what the justification was for aggregating the data in the way it was aggregated, or aggregating it at all in the first place, other than to contrive a statistic to argue for whatever policy position the authors already support. If the honest purpose of the study is to compare the results of various educational methodologies, I don't see that there'd be a useful unit of analysis any larger than an individual school, and even that might be too coarse. It's true that American states have de jure authority over public schools, and that there isn't any singular "American educational system" to speak of, but even within the individual states, there's still a great deal of variation from district to district and from school to school. Plus, there are plenty of schools outside the conventional public education systems, whose methodologies aren't determined by policy from any government.
