Spearman’s rank correlation coefficients for complexity by word count and Flesch-Kincaid reading grade level

	Trial A	Trial B	Trial C
Word Count	rho = 0.76; p < 0.001	rho = 0.79; p = 0.007	rho = 0.08; p = 0.860
Flesch-Kincaid Reading Grade Level	rho = 0.28; p = 0.090	rho = 0.50; p = 0.143	rho = 0.37; p = 0.374

Spearman’s rho ranges from 1.0 (perfect positive correlation) to 0 (no correlation)
