In this case study I will compare my state South Carolina with USA data and two other states Florida and Ohio. This research is basically to check on the COVID-19 confirmed cases and total deaths in USA and comparing the figures with that of my state South Carolina and also Florida and Ohio. For this case, I will use the information provided on COVID-19 cases for the month of March (Dong, 2020).

Statistics indicate that the population of the United States of America as of 2020 is estimated to be 331.0 million people (Barton, 2020). The state I live, South Carolina, has a population of approximately 5,210,095 as of 2020. During the month of March 2020, the United States of America confirmed a total of 925,940 cases of COVID-19. This implies that 0.28% of the total population was infected by the virus. From the 925,940 confirmed cases in March, total deaths was found to be 15,268. This is 1.65% of the total confirmed COVID-19 cases and 0.004% of the total United States population.

For my state, out of a total population of 5,210,095, 1093 cases of COVID-19 was confirmed from which 129 deaths were recorded based on the month of March (Dong, 2020). Therefore, 0.02% of the population in South Carolina was infected and 11.8% of the confirmed cases were deaths due to the COVID-19 infection. The state of Florida is known to have a population of approximately 22,992,985 by 2020. As of March 2020, Florida confirmed 6741 COVID-19 cases from which 473 deaths were recorded in the same month. This implies that 0.03% of the total population in Florida was infected by COVID-19 and 7.02% of the confirmed cases are deaths recorded during the month of March.

Ohio on the other hand had a total population of 11,747,694 as of 2020. In the month of March, Ohio recorded a total of 50619 COVID-19 cases which is 0.43% of its total population. However, 213 deaths were also recorded. This implies that 0.42% of the confirmed cases recorded in Ohio in the month of March resulted in deaths (Anderson, 2020).

Below are plots of the number of cases for United States, South Carolina, Florida and Ohio.

Below are plots of the number of deaths for United States, South Carolina, Florida and Ohio.

From the charts above, we can see that the number of cases of COVID-19 infection in USA increased continuously since the first day of March. For my state, South Carolina, the first case was recorded on the 7th day of March and the numbers generally kept increasing with few cases of decreases. The number of cases for my state can be said to be increasing slowly as compared to the number of cases in the entire country. Florida displays the same trend as that of my state, South Carolina, but the first case in Florida was recorded on 2nd day of March (WHO, 2020). Ohio displayed a continuously increasing trend of confirmed COVID-19 cases from the first day of March. Also, the number of cases for Ohio are generally higher than that of my state and the state of Florida. The charts on deaths show constant increase in the number of deaths of persons due to COVID-19 infection.

Presenting data in charts has a number of advantages in that, it provides for estimation of key values at a glance (Barton, 2020). Charts also have a better clarification of information as compared to tables. The presentation in charts also enables individuals who are not well conversant with numerical analysis to easily understand the information. Charts however, may oversimplify the data under study leading to misinterpretation of information.

Contingency Table

	Number of cases	Deaths	Total
South Carolina	1083	129	1212
Florida	6741	473	7214
Ohio	50619	213	50832
Total	58443	815	59258

From the charts and the contingency table above we can say that the number of COVID-19 cases keeps on increasing day by day and consequently deaths also increase. There is a higher probability of the number of cases and deaths getting higher than the number of cases and deaths getting lower (Anderson, 2020).

The table below shows descriptive statistics for the data obtained for my state, South Carolina and that of Florida on confirmed cases and the number of deaths caused by COVID-19 in March.

Descriptive Statistics
	N	Minimum	Maximum	Sum	Mean	Std. Deviation
ConfirmedcasesSC	31	0	158	1083	34.94	50.346
TotaldeathsSC	31	0	23	129	4.16	6.568
ConfirmedcasesFLORIDA	31	0	1268	6741	217.45	351.683
TotaldeathsFLORIDA	31	0	85	473	15.26	22.939
Valid N (listwise)	31

We can see that Florida has the highest mean number of cases as compared to that of my state, South Carolina. Florida also has the highest mean number of deaths. This result is might be as a result of a higher population in Florida than in South Carolina. Standard deviation tells us how much the values in the data differ from the mean value of the specific data. On average, a small standard deviation value indicates that the values in the data under study are close to the mean of the data set while a larger standard deviation means that the values in the data are much farther away from the mean (Dong, 2020). The descriptive statistics above show that the standard deviations of confirmed cases and deaths of Florida are generally higher than those of my state, South Carolina, simultaneously. This means that the values of the South Carolina’s data set are closer to their means on average than those of Florida.
