This table shows the average values for the real sparseness, ${\overline{s}}_{3\text{-paired}}^i$, as well as the mean values of the average random sparseness, $\overline{{\overline{s}}_{\text{rand}}^i}$, for both evaluation procedures i ∈ {1, 2}, see Materials and Methods for the detailed definitions. The pⁱ-values estimate the probability that the average sparseness value is larger than the one for randomly chosen codons.
