Results of cod inter-reader precision test
using randomly selected Gulf of Maine samples from the 2004 NEFSC autumn survey.
(A) Age-bias plot, showing the average age attained by NM versus the ages attained by NS.
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 NM; those
below the shaded boxes were given higher ages by NS. Total age
frequencies are given by age for both readers. (C) Results summary, indicating NM's results
relative to each of NS's ages.
