<p>Your link identifies the denominator as “per capita”. NOT per capita biology majors.
In MY NSF link in #12 above there is a similar chart to #10, Table 4, with some different ordering of schools. Possibly due to data from different years. It explicitly states that the denominator is everybody that graduated from the school, in any major. ie NOT just biology majors.</p>
<p>To quote:
“The “institutional-yield ratio” for a baccalaureate-origin institution for a given year is expressed as the number of S&E doctorate recipients per 100 bachelor’s degrees awarded in ALL FIELDS* 9 years earlier”
(* caps are mine)</p>
<p>Perhaps you can find a specific link to some different nsf data that explicitly states the the denominator is just biology majors, and not “degrees awarded in ALL FIELDS”??
