RE: If you took a like demographic pool in the two groups
What is a like demographic pool ?
“What is a like demographic pool ?”
Compare a population of kids from homeschool families and public school families - where both are 2-parent familes, same income ranges, and same educational attainment.
These would be “like demographic pools” for statistical purposes.
Comparing white, 2-parent middle class parents with college degrees with a pool of single parent, poor families with GED’s would yield an irrelevant statistical comparison (for deciding which type of education is “best”)
