Exploration of COVID-۱۹ Pandemic Using Variety of Frequency Tables

The coronavirus disease was first discovered in Malaysia on the ۲۵th of January, ۲۰۲۰. The number of positive cases remained stable until March ۲۰۲۰, where a large spike emerged. Different exploratory data analysis tools need to be used to easily observe the trend of coronavirus infections and ascertain the end of the pandemic. Also, the growth rate of the pandemic seems to be under-reported in many countries due to some issues. In this research, we explored the reported COVID-۱۹ data using different discrete frequency tables. The positive cases, deaths, and recoveries were organized in general cases, cumulative cases and ۱۴ days moving cases frequency tables. The reported positive cases were displayed according to the states as states' new cases, cumulative cases, and ۱۴ days moving cases frequency tables. The end of the pandemic can be detected when there is no infection for ۱۴ consecutive days and was determined in the country as a whole using the cumulative cases and the ۱۴ days moving cases general frequency tables. Whereas in the states, the states' cumulative cases and the ۱۴ days moving cases frequency tables were used to detect the end of COVID-۱۹ pandemic.
