Figure 2. Standardized mean differences showing the balance improvement obtained by propensity score matching for college attendance and nonattendance, among the cohort of youth (<18 years) who aged into early adulthood (18-24 years) between Waves 1 and 3 of the PATH Study, United States, 2013-14, 2015-16.

Figure 2.

Note: Each dot in the figure indicates the standardized mean difference of the covariate between attenders and nonattenders in either the unmatched sample (grey dots) or in the matched sample. Nearest-neighbor matching was used to balance the matched sample with a 1:1 matching ratio and a caliper of 0.1. Standardized mean difference values <∣0.1∣ indicate good balance.
