One school has a directional average-net-price path over 2015–2023; the other sits in a measured range (or the two move opposite ways). Cost gaps on this board are moving targets.

• HCA Florida Mercy Hospital School of Practical Nursing: average net price rose +124.7% from $4,304 (2015) to $9,672 (2023), r² 0.83.
• California Barber and Beauty College: net price ranged $8,814–$10,810 across 9 years (2015–2023); endpoint change -0.9% is not a trend (r² 0.34).

College Scorecard institution series; dollars are nominal. Direction claims require r² ≥ 0.40 on the fitted annual slope, otherwise the page reports the observed range. Descriptive history, not a recommendation.
