Results of tilefish precision test using randomly selected samples from all quarters of the 2007 NEFSC commercial samples. (A) Agreement plot, showing both the production and test ages. A small amount of noise was added to the data to improve visibility of overlapping data points. (B) Age-frequency table, showing the test ages across the top and the production ages on the left. Numbers in the shaded boxes indicate agreement between the two ages. Numbers above this diagonal indicate fish which were under-aged during the test; those below the shaded boxes were over-aged. Total age frequencies are given by age for both the test and production ages. (C) Results summary, indicating results of the test for each production age.
