Best I could find was "SAT patterns and engineering and computer
science college majors: an intersectional,
state-level study"
It looked at Virginian public school graduates. Non-URM (underrepresented minority) men and non-URM women who majored in computer science scored similarly on the math part of their SATs. Women scored 3% better on their verbal.
Your quote doesn't address the self-selection question.
In fact, taking that paper, it suggests that males are about 30-100% or even more more likely to enroll in an ECS major across the range of math scores.
For example, among those participants with a math score of 700, about 15% of females vs 30% of males end up enrolling in an ECS major.
