Results of goosefish inter-reader precision test against randomly selected samples from the 2001, 2002, and 2005 NEFSC commercial samples. (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 KL; those below the shaded boxes were given higher ages by SS. Total age frequencies are given by age for both readers. (C) Results summary, indicating SS's results relative to each of KL's ages.
