Results of summer flounder inter-reader precision test
against randomly selected samples from the 2016 NEFSC spring survey. Otoliths were used for age determinations. (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 ER. Total age frequencies are given by age for both readers. (C) Results summary, indicating ER's results relative to each of BJ's ages.
