against randomly selected samples from the 2009 NEFSC autumn survey.
(A) Agreement plot, showing the ages attained by each reader. A small amount of noise was added to the data to improve visibility of overlapping data points. (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 JB; those
below the shaded boxes were given higher ages by JD. Total age
frequencies are given by age for both readers. (C) Results summary, indicating JD's results
relative to each of JB's ages.
