Results of butterfish inter-reader precision test
using randomly selected samples from the 2003 NEFSC spring survey.
(A) Age-bias plot, showing the average age attained by LD-W versus the ages attained by NM.
Error bars indicate
95% confidence intervals. (B) Age-frequency table, showing each reader's ages. Numbers
in the shaded boxes indicate agreement between the two
readers. Numbers above this diagonal indicate fish which were given higher ages by LD-W; those
below the shaded boxes were given higher ages by NM. Total age
frequencies are given by age for both readers. (C) Results summary, indicating LD-W's results
relative to each of NM's ages.
