CRD 07-15 Table 1. Percent of records replaced by median values by type of data
Source	Hauls	Soak Time	Mesh Size	Gear Size
No change - original data used	97.75	98.34	98.11	93.95
Data replaced by first stratified median^a	1.56	1.12	1.18	2.8
Data replaced by second stratified median^b	0.57	0.54	0.71	3.25
Records set to zero	0.12	-	-	-
^aMedian values were calculated by stratifying trips based on hull number (vessel), gear type, FMP, year, and state, so that each unique combination of these variables had a matching median. ^bMedian values were calculated by stratifying trips based on gear type, FMP group, year, and state, so that each unique combination of these variables had a matching median. That is, the same stratification as for the first median, except vessel identification information (hull number) was removed.
