In this paper, we propose a new Kumaraswamy distribution. We then present some statistical and reliability properties of the new distribution. We use the maximum likelihood estimation technique to estimate the model parameters. In order to illustrate the usefulness of the proposed model, we fit the model to three real data sets and compare its relative performance with respect to the beta generalized Weibull family.
