2.Global efforts around the world are focused on to discuss several health care strategies for minimizing the impact of the new coronavirus (COVID-19) on the community. As it is clear that this virus becomes a public health threat and spreading easily among individuals. Mathematical models with computational simulations are effective tools that help global efforts to estimate key transmission parameters and further improvements for controlling this disease. This is an infectious disease and can be modeled as a system of non-linear differential equations with reaction rates.

3.While quantitative results may help to identify how many students participate in university sports, a qualitative analysis is useful in exploring participants' needs and providing concrete suggestions for program improvement.

4.Quantitative research in education provides numerical data that can prove or disprove a theory, and administrators can easily share the number-based results with other schools and districts

5.Qualitative research allows us to investigate and discover new processes of political communication..
