The Standard Model is widely accepted as one of the most successful predictive theories of Physics, providing insight into the fundamental building blocks of the universe. Over the last few decades this model has shown signs of incompleteness, most of which are attributed to Neutrinos. Within the confines of the standard model a discrepancy exists related to vanishing Neutrino masses, which contradicts the experimental observation of Neutrino Oscillation. Neutrino oscillation depends on 7 parameters (3 mixing angles $\theta_{12}$, $\theta_{23}$, $\theta_{13}$, a Dirac Phase due to CP violation $\delta_{CP}$, and the 3 mass states $m_1$, $m_2$, $m_3$). Values of the parameters $\theta_{12}$, $\theta_{13}$, $\Delta m^2_{21}$, $|\Delta m^2_{32}|$ are well determined whilst $\theta_{23}$, $\delta_{CP}$ and the mass Hierarchy, whether ($m_1< m_2
