In this paper, we consider a flexible skew-generalized normal distribution. This distribution is denoted by FSGN(λ1, λ2; θ). It contains the normal, skew-normal (Azzalini, 1985), skew generalized normal (ArellanoValle et al., 2004) and skew flexible-normal (Gomez et al., 2011) distributions as special cases. Some important properties of this distribution are established. Also, the practical usefulness of FSGN is illustrated via a well known real data set.
