Do you know of a equivalent paper for ethnic groups? All the data is present in NAEP datasets.
Speaking of the sex differences in variance. This paper looked at all the NAEP data for reading and writing -- huge & natl US samples collected for 30 years. Male variation is still larger and grows with age. This offsets girls mean advantage at far tail https://www.apa.org/pubs/journals/releases/amp-amp0000356.pdf …pic.twitter.com/qpzblqkXFT

I don't know a such paper, but it's easy to find papers about mean differences in NAEP.

Really wish this stuff would be presented in meaningful terms/quantities. E.g. https://twitter.com/SilverVVulpes/status/1044998035921670144 …. I've been convinced greater male variance is likely important in understanding a lot of politically relevant sex discrepancies, but without tethering to real-world relevance...
