TABLE 6.

Mean Words Correct per Minute for Measures of Word Reading Efficiency and Oral Reading Rate as a Function of Reading Group

Group	Word Reading Efficiency (SARA Word Recognition)	Oral Reading Rate (SARA Passage Reading)	Within-Group Contrasts^a (Cohen’s d)
AVG^b	75.94 (14.75)	154.60 (23.46)	−3.64^***
WRD^c	52.39 (19.59)	100.41 (32.70)	−2.33^***
S-RCD^d	70.02 (14.66)	132.83 (24.12)	−3.22^***
Between-group contrasts^a (Cohen’s d)
AVG vs. WRD	1.28^***	2.28^***
AVG vs. S-RCD	0.18	0.71^*
WRD vs. S-RCD	−1.13^***	−1.63^***

Note. AVG = average readers; WRD = poor decoders; S-RCD = poor comprehenders.

Contrasts covarying for Age and Matrix Reasoning, raw score.
