Data Handling and Using: ICT

This presentation explores data handling using information and communication technology (ICT) in the context of COVID-19 cases. It covers statistical techniques, data manipulation, and graphical representation. The analysis reveals the rise and decline of cases in different regions, with America experiencing the highest increase and Western Pacific the lowest. The average, median, mode, sum, and percentage of cases are calculated and presented. The conclusion highlights the impact of the pandemic and the expectation of returning to normalcy in 2021.

Introduction
Data handling using information and communication technology becomes a lot easier in
collecting, summarising, presenting and analysing. This presentation is researching about the
cases of onset and spread of COVID-19 in the world. It is a global pandemic which started from
Asia and soon reached to all parts of Europe. It registered its first break in later part of December
2019 in Asia and spread to the world in first quarter of 2020. World Health Organisation (WHO)
is responsibly monitoring the situation. Data has been obtained for the figures of the cases
present at the end of four quarters of the year 2020. Further, raw data obtained has been
converted into meaningful information by applying statistical techniques like percentage, mean,
median and mode. Furthermore, in order to present the information into visually understandable
types, it has been converted into graphical format to present the analysed data.
Raw data Presentation
World Health Organisation (WHO) is responsibly monitoring the situation and to tackle the
information in an organised manner, it divided the world in six regions - America, Europe,
South-East Asia, Eastern Mediterranean, Africa and Western Pacific (WHO Coronavirus
(COVID-19) Dashboard, 2021). For this assessment, data has been obtained for the figures of the
cases present at the end of four quarters of the year 2020.
In the above table, figures of the six regions at the last date of end of four quarters has been
demonstrated above. It can be seen that America registers the most number of cases while
western pacific has registered least number of cases.

Statistical techniques
Statistical techniques are those of statistics which are applied on raw data to present them into a
meaningful information. Below mentioned is application of statistical techniques on the COVID-
19 data:
A. Mean
Mean refers to the average of a data expression. For calculating the mean of data expression, sum
total of data expression is obtained and is then divided by the count of numbers in the expression.
In the data-set used, world has been divided into six regions which means count of numbers
comes down to 6. Below mentioned is mean calculation for the data set:
Mean (M) = Sum of the terms (∑X) / number of terms (N)
B. Median
Median is used to find out middle value of the series. In order to find median, a data set has to be
first arranged in either ascending or descending order. Then, for odd-numbered series, ((N+1) /
2)th observation is taken as median and for even numbered series, median is the value of ((N/2) +
(N/2 + 1) / 2)th observation. Below mentioned is the median calculation for the above data set:

C. Mode
Mode refers to that value in a data expression which is being repeated frequently. Since, there is
no repetition in the number or value of data, there is no mode in this data set. It can be owed to
expression that COVID-19 cases are rising all over the world, they are neither stagnating nor
declining to have a repetition in the values.
Data Manipulation
A. Sum
Sum refers to the technique of summation. It is used to determine the total number of cases that
were present in the world at that time. In excel, sum() function is used to sum data set. Below
mentioned is the application of the sum function in excel worksheet.

B. Average
Average refers to the technique of determining mean of the data set. It is used to determine the
average number of cases that were present in the world at that time in the reported quarter. In
excel, average() function is used to find average of data set. Below mentioned is the application
of the average function in excel worksheet.

C. Count
Count refers to the technique of determining total number of types of data in the set. It is used to
determine the count of number of regions that the world was divided by WHO to have
streamlined reporting. In excel, count() function is used to count the number of data set. Below
mentioned is the application of the count function in excel worksheet.

D. Max
Max refers to the technique of determining largest value in the data set. It is used to determine
the region with maximum number of reported case in that quarter. In excel, max() function is
used to determine the largest number of data set. Below mentioned is the application of the max
function in excel worksheet.

the region with minimum number of reported case in that quarter. In excel, min() function is used
to determine the largest number of data set. Below mentioned is the application of the min
function in excel worksheet.

Graphical representation
From the above graph, it can be seen that America has seen most rise in the number of cases
while Western Pacific has seen least rise in the rate of increase in cases. Further, South-east Asia
is the only region which has seen a decline post third quarter and Africa is the region which has
seen ups then downs and then again ups.

Conclusion
Above assessment has been on data handling using information and communication technology.
Data for the COVID-19 cases across the six regions of the world, as divided by the WHO has
been taken in the consideration for the four quarters of the year 2020. It can be concluded from
above analysis that America has seen most rise in the number of cases while Western Pacific has
seen least rise in the rate of increase in cases. Further, South-east Asia is the only region which
has seen a decline post third quarter and Africa is the region which has seen ups then downs and
then again ups. Other than data analysis in the graphical presentation, statistical techniques has
also been applied to evaluate the various metrics related to the raw data undertaken for the
research. From mean,it can be seen that average number of cases gradually see only increment.
Median, on the other hand has seen ups and downs in the four quarters. Since, there was no
repetition in the numbers of data, there was no modal value. All this data in a summary present a
picture of the situation that has been prevalent all over the world. It represents the situation that
has stopped the world at one point of time. However, with the passage of time, prevention and
post vaccination, things are improving and are expected to return to normalcy in the year 2021.
