q3 i? For every standard deviation increase in HSGPA, the odds of graduating from college double (odds coefficient = 2.02), and the linear slope does not vary significantly by high school. → Allensworth 2019

q3 · i? · associational · r3

Hierarchical logistic models of six-year college graduation for 17,753 CPS four-year college enrollees, controlling for student background and college institutional variables. The article reports the "odds coefficient = 2.02" for standardized HSGPA and that the linear slope does not vary significantly by high school.

"The linear component shows that for every standard deviation increase in HSGPA, the odds of graduating from college double (odds coefficient = 2.02) at the point where the quadratic term is zero"

Discussion¶

Related Claims¶

• Adding ACT scores to models with HSGPA contributes little to the prediction of college graduation and does not reduce between-school variability — related
• ACT scores show a weak relationship with college graduation, with slope variation across high schools larger than the average signal — related
• Both HSGPA and ACT strongly predict four-year college enrollment and enrollment in colleges with strong graduation rates — related
• The linear slope of the HSGPA–college graduation relationship does not vary significantly across high schools, so HSGPA provides a consistent signal across schools — possibly the same claim (merge candidate)
• HSGPAs have a strong, consistent relationship with college graduation that is larger than school effects, while ACT scores have a weak relationship smaller than high school effects with slopes varying by school — related
• HSGPA strongly predicts six-year college graduation among four-year college enrollees, with odds of graduating doubling per standard deviation of HSGPA — possibly the same claim (merge candidate)
• For four-year (rather than six-year) graduation, ACT scores are slightly predictive but their coefficient is one-sixth the HSGPA coefficient — related
• Increasing high school GPA by 0.4 points has a larger impact on four-year college graduation than increasing ACT by 2 points for CPS students of all academic qualifications — related
