This paper introduces the transmuted generalized power Weibull distribution by using the quadratic rank transmutation map technique (QRTM) and derive some of its structural properties. This paper formulates the expressions for the moments and probability weighted moments. The method of maximum likelihood is used for estimating the model parameters and evaluate the performance of MLE using simulation. An application to data on anxiety is discussed to illustrate the flexibility of the new distribution.
