Notes: Sample size A = sample size when including books in the home, mother's education, and articles in the home. Both BH and BH+ME. Sample size B = sample size when including books in the home, highest parental education, and articles in the home. Correlations shown for sample size A all use the same observations in sample A; correlations shown for sample size B all use the same observations in sample B.
