On the basis of several common internal properties among the best known power indices, a subset in the imputation set to which standard power indices belong is considered. This notion gives rise to an interval of power that assigns intervals of real numbers to the players. Power indices based on marginal contributions are generated and a second notion of interval which contains Shapley–Shubik and Banzhaf indices for every game is considered.
