Note: In the first chart the tallies for Gray code is missing one line. "2 x 15" should follow "2 x 13". | Note: In the first chart the tallies for Gray code is missing one line. "2 x 15" should follow "2 x 13". | ||

In both cases the mean degree of change is 3.75. In the case of binary codes there are as many transitions above the mean as below the mean. But in the case of gray codes 44 transitions are below the mean and 20 transitions are above the mean. Gray code provides a system where mutations result in a greater number of small changes, and a lesser number of large changes. | In both cases the mean degree of change is 3.75.
