None. Purdue University has 48 left-framed courses and not one right-framed course.

Why this number, in plain words

Political lean of course descriptions. Average Framing score (0 = far right, 50 = center, 100 = far left) of the scored courses in the group.

50 is the survey-anchored center of US adults on each issue (the "moderate" place of the ANES/GSS/PRRI seven-label ruler), not the cohort midpoint; scores above 50 read leftward, below 50 rightward.

Counted: courses with a Framing score (categories L/R/B/C). The likely range (95% interval) is 63.2 to 67.6; a comparison whose range overlaps this one is not a reliable difference.

Most course descriptions carry no political lean at all and are not in this average; the "share described from the left" view counts them.
Readings are of catalog description text, not of teaching, syllabi or individual professors.

Lean (mean Framing score) is not published per department within a school; only the left-framed share is. Department rows carry no interval.

Interval: normal approximation: mean +/- 1.96 * sd / sqrt(n), sample sd (n-1); undefined when n < 2

Metric caveats: Scored courses only (L/R/B/C); N and I carry no score and are excluded, so n here is smaller than the group's course count. Scores are model readings of catalog description text against a fixed anchored definition, not teaching or syllabi. The interval covers sampling noise in the mean only; it does not represent model reading error. Every value carries a `method` label: exact_rows or histogram_midpoint.
