Here is a graph displaying the mean of the Math, Science and Reading test scores from the OECD's 2012 Program for International Student Assessment (PISA)

How come Massachusetts, Connecticut, and Florida, are listed separately from the "United States", and separate from the sub-categories for the United States : "White Americans", "Asian Americans", "Multi-racial Americans", "Hispanic Americans", and "African Americans" ?

Why are these three states listed as separate from the "United States" and above-mentioned sub-categories for the United States? And considering they're listed separately, are the IQ figures from Massachusetts, Connecticut, and Florida, excluded in the overall IQ figure for the "United States" ? Are the IQ figures for the USA sub-categories from Massachusetts, Connecticut, Florida, excluded in figures of the sub-categories, as the 3 states are listed as somehow being separate from the USA and separate from all the sub-categories for the USA ?

Why are these three states listed as somehow being separate? They are listed separately from the "United States" and separate from the various categories for the USA. If these 3 states are considered to be "sub-categories" also, then why shouldn't all 50 states be listed as sub-categories as well?

Why are Massachusetts, Connecticut, Florida, listed as being somehow separate from the USA and the sub-categories for the USA? It implies the 3 states are somehow sovereign. Very strange.

I believe that those 3 states are listed separately to give an idea of how students are doing in different parts of the country. I believe that all 50 states are included under the United States category.
