|Results of Atlantic herring inter-reader precision test
using randomly selected samples from the 2005 NEFSC acoustic 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 BJ; those
below the shaded boxes were given higher ages by SE. Total age
frequencies are given by age for both readers. (C) Results summary, indicating SE's results
relative to each of BJ's ages.
