In this research article, we introduced the notion of q-probabilty distributions in quantum calculus. We characterized the concept of q-density by connecting it to a probability measure and investigated some of their outstanding properties. In this case, the Transfer theorem was extended in order to compute afterwards the q-moments, q-entropy, qmoment generating function, and q-quantiles. We are also interested in finding the centered q- Gaussian distribution Nq(0, sigma 2) with variance s2. We also proved that this q-distribution belongs to a class of classical discrete distributions. The centered q-Gaussian law Nq(0, s(2)) is also naturally related to the q-Gaussian distribution Nq(mu, sigma(2)) with mean mu and standard deviation s. We corroborated that the q-moments of these q-distributions are q-analogs of the moments of classical distributions. Numerical studies demonstrated that Nq(0, sigma(2)) interpolates between the classical Uniform and Gaussian distributions when q goes to 0 and 1, respectively. Subsequently, simulation studies for various q parameter values and samples sizes of theGaussian q-distributionswere conducted to demonstrate the effectiveness of the proposed model. Eventually, we provided some pertinent closing remarks and offered new perspectives for future works.
