Table 2.

Descriptive statistics for speech perception group data. Values at individual SNRs are displayed in percentage correct. Slope values are displayed in percent-per-dB. IQRs are displayed as first and third quartiles, respectively. SNR indicates signal-to-noise ratio; CRM indicates coordinate response measure; IEEE indicates Institute of Electrical and Electronics Engineers; IQR indicates interquartile range.

Speech Test	SNR (dB)	Median	IQR	Minimum	Maximum
CRM	-9	28	20 to 37	8	56
	-6	62	55 to 65.5	36	74
	Slope	10	7.5 to 11.7	6	15.3
IEEE	-6	17	13.3 to 24	3	45
	-3	56	21 to 62	12	80
	Slope	10	4.4 to 13.3	-1	22
