Thank you for the responses. Looking at the CDS for Rutgers and Villanova, the SAT scores do closely match data posted by external sites like U.S. News and Niche.
I also confirmed that the CDS data is for enrolled students, while admissions info like the below from Rutgers specifies admitted students. (I had suspected that already, but I didn’t notice the source of data from external sites.) In cases where less than a third of admitted students accept their offer and enroll the difference between admitted and enrolled students makes sense.
