Okay, look - they're different. Some of them look like they're even statistically significantly so. Here's what's missing:Of course it does.No it doesn't.
The real question is: do you?You would need to not understand what an "average" is to claim that. I'm pretty certain you understand what the word "average" means.
Not necessarily.If the acceptance rate was equivalent despite the difference in MCAT / GPA scores or the acceptance rate was random or reversed as shown relative to MCAT / GPA, that would provide evidence of your claim.
Slightly better chance of acceptance, yes. But because the applicant pools have very different stats, the slightly different acceptance rates do not begin to compensate for that. That means that among matriculants, not applicants, there are still vast differences in grades and scores. I did an analysis of the MCAT data earlier. Let me post it again.Instead, the stats above show that higher score/GPA means you have a better chance at acceptance.

Look at the vast difference of where the black and Hispanic confidence intervals are compared to white and Asian ones. American Indian and Alaska Native have an even worse mean MCAT, but their numbers are so low, the confidence interval is wide and approaches black and Hispanic CIs.
- What is the overall mean and standard deviation of the population as a whole, and how representative is the sample?
- Do the ranges of the cohorts fall within the range of the population as a whole in a way that suggests sampling error is the more likely explanation for the differences?
- Is there bias or skew in the sample selection criteria, either intentional or inadvertent?
And most importantly:
It's a constant annoyance to me. There are tons and tons of things out there where you can create a division on some identifiable characteristic, and if you look at the results for each cohort, find a statistically significant variance. But if you step back and look at the range of possible outcomes, the absolute difference between the means and their ranges is only a very small wedge. The difference is not material.
- Is the difference material?
I’d like to add a few more points to build on this: (1) MCAT scores are not the sole metric for admissions. Committees weigh multiple factors, and these variables often distribute differently across the demographic groups being discussed. (2) The groups under discussion do not apply to or attend the same tiers of schools at identical rates. For example, Historically Black Colleges and Universities (HBCUs) educate roughly 10% of African American college students. Because different subsets of institutions often have different baseline criteria or flexibilities, comparing the entire national applicant pool as a single monolith is misleading. (3) Many medical schools actively recruit candidates who commit to working in underserved communities. This specific mission inevitably influences acceptance rates differently among the demographic groups being discussed.
While I don’t deny that race can factor into individual college admissions decisions at times, relying on uni-dimensional averages to make sweeping claims about systemic unfairness lacks intellectual rigor. Pointing to average differences in a single variable does not mathematically prove vast unfairness—more often than not, it could be an apples-to-oranges comparison hiding behind a graph. Serious discussions about race and admissions require far more rigor than just whipping out this same chart every time affirmative action, SATs, or DEI comes up.
Since this is a derail, I have created a thread for discussion of MCATS:
This is a space to discuss these things without derailing some other threads about current events. In particular, US college admissions into pre-med schools has come up and different averages across demographic groups in MCATs and how that could play a role.
