_D_e_t_a_i_l_s:

     In a regional ecology study, plots of land of equal area were
     inspected  and the parts of each plot which were thick or thin in
     vegetation and dense or sparse in animals were identified. From
     this field work the areal proportions of each plot were calculated
     for the four mutually exclusive and exhaustive categories:
     thick-dense, thick-sparse, thin-dense, thin-sparse. These sets of
     proportions are recorded for 50 plots from each of two different
     regions A and B. 

     All rows sum to 1, except for some rounding errors.
