—Relationships Between Scores From Five Naive Readers and the Control Scores

Reader	Intercepta	Slopeb
A	−3.5	1.2
	−5.6 to −1.7	1.1 to 1.4
B	2.1	1.0
	0.6 to 3.4	0.9 to 1.1
C	0.6	1.0
	−2.0 to 2.7	0.8 to 1.2
D	−0.3	1.0
	−2.2 to 1.3	0.8 to 1.1
E	−0.8	1.0
	−2.5 to 0.6	0.9−1.2

^aThe intercept represents the amount of fixed bias, the naive reader score when the control score is zero.

^bThe slope represents the amount of proportional bias, the change in naive reader score when the control score changes by 1 unit.
