Results of summer flounder inter-reader precision test
against randomly selected samples from the first quarter of the 2009 commercial samples from the Partnership for Mid-Atlantic Fisheries Science. Scales were used for age determinations.
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 NC. Total age frequencies are given by age for both readers. (C) Results summary, indicating NC's results relative to each of BJ's ages.
