Interpreting relative weight ( W r ) data can be facilitated by comparing mean W r values in a sample to percentiles from a cumulative frequency distribution of population‐mean W r values from populations sampled over the range of the species. We developed a cumulative frequency distribution of population‐mean W r values for length categories of lake trout Salvelinus namaycush across their North American range. Then, we compared W r values from seven populations in Wyoming to the cumulative frequency distribution of population‐mean W r values to gain insight into lake trout population status.
