"WebThe maximum value of entropy is log k, where k is the number of categories you are using. Its numeric value will naturally depend on the base of logarithms you are using. Using base 2 logarithms as an example, as in the question: log 2 1 is 0 and log 2 2 is 1, so a result greater than 1 is definitely wrong if the number of categories is 1 or 2.
